citrix desktop service manual startup

This means that as soon as the autologon account logs off, the service will start and register with the Delivery Controller(s). When this happens, and depending on how quickly the the VDA registers with the Delivery Controller, it may cause a power managed VDI machine to reboot again; creating a reboot loop. This is simply a timing issue. So to work around this, we also wait for the logoff event. Typically when you correlate logon and logoff events you can “tie” events 4624 (logon) and 4634 (logoff) together using the “Logon ID” value, which is a unique hexadecimal code that identifies that particular logon session. We can, however, tie it to the 4647 (logoff) event. However, this event just tells us that the logoff was initiated and not complete. A 4634 (logoff) event will follow, but there is no information in that event which allows us to formally tie them together. Therefore, we make the assumption that the 4634 event that follows the 4647 event is the actual termination of the logoff. This allows us to start the Citrix Desktop Service without the risk of a reboot loop occurring. I will be writing further articles to explain how I implemented post VDA install tasks and the autologon and logoff process. You don’t need to worry about this as part of your initial implementation. Simply start by using the DelayDesktopServiceTime value and you can enhance this at a later date. His skill set, high ethical standards, integrity, morals and attention to detail, coupled with his friendly nature and exceptional design and problem solving skills, makes him one of the most highly respected and sought after Microsoft and Citrix technical resources in Australia. His alignment with industry and vendor best practices puts him amongst the leaders of his field. This is divided into Workspace App Session Startup and VDA Session Startup duration on the User Details page and Machine Details pages.

• citrix desktop service manual startup.

It’s important that the priority of the Scheduled Task is set to normal to prevent it from being queued. You’ll see from the screen shot of the log file below that it’s now quite comprehensive. I’ve got it to a point where it works perfectly for my needs, and has been very reliable over the last few months, so I decided it was ready to release to the community. When this happens it may fail the session launch, which can leave the Session Host in an unhealthy state, such as a stuck prelaunch state, with the user potentially needing to involve the Service Desk to clear the issue. So managing the timing of the start of the Citrix Desktop Service (BrokerAgent) is extremely important to ensure that your Session Hosts have completed their startup process before registering with the Delivery Controllers. This can be easier said than done! I use an autologon process similar to what George Spiers documented in his article “ Reduce Citrix logon times by up to 75% “. So if the Session Host has registered with the Delivery Controllers before the autologon process has logged off, the logoff process will trigger another reboot. This can become a real problem to manage. I had varying success with the tool. He left Citrix and no one took over the development and upkeep of this tool. As it was an unsupported Citrix tool with no ownership, I decided to stop using it and write my own, which included the logic I was after. Plus, my goal was to write it in PowerShell. I wanted it to do 3 things: This ensures Group Policy has applied, and you’re not starting the service with an empty list, or an invalid server.This is the cool bit where I can make it an exact science. As mentioned, I use an autologon process, so I have another Scheduled Task called “Session Host Autologon Logoff Task”, which logs off this autologon session. This of course writes the logon and logoff events to the Windows Security Event Log, so the script simply triggers based on those events.

When this duration is high, it indicates that the STA server or the Delivery Controller are overloaded. The check is performed on the client to determine whether an existing session can handle the application launch request. The method used depends on whether the session is new or shared. When this metric is high, it indicates that there is a VDA issue increasing session start times. This includes the time spent on the VDA performing the entire start-up operation. So, it is not included in the VDA Startup Duration. This time is likely to be a significant only if manual login is being used and the server side credentials dialog is displayed (or if a legal notice is displayed before login commences). They can be Kerberos, Active Directory, or a Security Support Provider Interface (SSPI). Consider optimizing any application compatibility scripts or use environment variables instead. Roaming profile size and location contribute to slow session starts. When a user logs on to a session where Terminal Services roaming profiles and home folders are enabled, the roaming profile contents and access to that folder are mapped during the logon. This takes extra resources. Sometimes, this can consume significant amount of the CPU usage. Consider using the Terminal Services home folders with redirected personal folders to mitigate this problem. In general, consider using Citrix Profile Management to manage user profiles in Citrix environments. If you are using Citrix Profile Management and have slow logon times, check if your antivirus software is blocking the Citrix Profile Management tool. If the configuration is set for printer creation to be performed asynchronously, the value is not recorded for PCVD as it does not impact completion of the session startup. The number of printers added locally on the users’ client devices and your printing configuration can directly affect your session start times.

These two durations further contain individual phases whose startup durations are also displayed. This data helps you to understand and troubleshoot high session startup duration. Further, the time duration for each phase involved in the session startup helps in troubleshooting issues associated with individual phases. For example, if the Drive Mapping time is high, you can check to see whether all the valid drives are mapped correctly in the GPO or script. This feature is available on Delivery Controller version 7 1906 and later and VDAs 1903 and later. For earlier versions, IFDCD is displayed for only app launches from the browser with Workspace app detected. For shared sessions (multiple applications launched in the same session), the Workspace App Startup metrics are displayed for the latest connection or the latest application launch. In such cases, a message is displayed. Review subsequent metrics to determine the probable root cause of the issue. SSCD starts as close as possible to the time of the request (mouse click). It ends when the ICA connection between the client device and VDA has been established. In the case of a shared session, this duration is much smaller, as much of the setup costs associated with the creation of a new connection to the server are not incurred. At the following level down, there are several detailed metrics available. The overall process is as follows: Also, StoreFront requests and receives a one-time ticket from the Secure Ticket Authority. This results from network issues between the two machines. So you can troubleshoot potential network issues first. If LPWD is high, there might be a bottleneck on the StoreFront. Try to identify the cause of the slowdown by checking the Internet Information Services (IIS) logs and monitoring tools, Task Manager, Performance Monitor and so on. Check if the network connection between StoreFront and Delivery Controller is slow or some Delivery Controllers are down or overloaded.

If not, right-click the service, select Properties, and then, in Startup type, select Automatic See Before doing this, verify the Print Spooler service is running on the machine. Note: The Print Spooler service is required for successfully installing the VDA software for Windows Server operating systems. If the Print Spooler service is stopped, right-click the service and select Start. As with other products (Citrix or other vendors), there is a wide variety of possible causes of these communication problems. My intention with this blog post is to create a single resource that you can use to start your troubleshooting in order to resolve your issue as quickly as possible. Here are the top five common mistakes listed and how to resolve them: This configuration allows for flexibility and centralized management. Just ping the DDC’s FQDN from the VDA and check if it can be resolved and vice versa from the DDC (ping the VDA FQDN). In this situation, you can set the startup type to Delayed auto start instead of Automatic Startup. Another reason for the service not starting is that the startup type is set to Manual. In this case, change the startup type to Automatic startup. This can affect the services that use the Microsoft.NET Framework in particular. By design, Microsoft.NET processes require additional overhead to start the process. These include: If the service is in stopped state, try starting the service and check if this has fixed the Time Sync issue and the VDA is registering correctly. Additionally, verify if the pooled desktops join the domain correctly after boot. Using gpresult, verify if the NT AUTHORITY\NETWORK account is still listed as a user that can access the computer (VDA) from the network. With an easy to use update tool included, you will always have the best and latest troubleshooting toolkit at your disposal.

When a session starts, Citrix Virtual Apps and Desktops have to create every locally mapped printer on the client device. Consider reconfiguring your printing policies to reduce the number of printers that get created, specifically when users have many local printers. To do this, edit the Printer Auto creation policy in Delivery Controller and Citrix Virtual Apps and Desktops. For example, audio or COM port mapping, to optimize the ICA protocol and improve overall session performance. When a user logs on to a Windows machine, winlogon runs userinit.exe. Usernit.exe runs logon scripts, re-establishes network connections, and then starts Explorer.exe. Userinit represents the duration between the start of userinit.exe to the start of the user interface for the virtual desktop or application. The Shell duration is the time between the initialization of the user interface to the time the user receives keyboard and mouse control.

If the difference in system time between the two ends of the communication is too great, the Tickets are always considered to have timed out when they are accessed and communication fails.This can cause problems with the secure communication between virtual desktops and controller.When the subsequent system restart has completed, check to see if registration has been successful. The services implementing the communication endpoints use the computer’s identity. The controller determines the virtual desktop’s SPN after inspecting the servicePrincipalName attribute of the associated computer account in Active Directory.If the servicePrincipalName attribute does not include an entry with the computer’s fully qualified domain name, try editing it manually, and check to see if that fixes registration problems. In that case, try disabling all network adapters except for the one used to communicate with the controllers.This behavior is described in. End users can use applications and desktops independently of the device’s operating system and interface. You maintain complete control over applications, policies, and users while delivering the best user experience on any device. Cloud Connector enables cloud management without requiring any complex networking or infrastructure configuration such as VPNs or IPsec tunnels. Resource locations contain the machines and other resources that deliver applications and desktops to your subscribers. Citrix also takes care of installing and upgrading those components. (This differs from an on-premises Citrix Virtual Apps and Desktops deployment, where you are responsible for installing, managing, and upgrading the core components.) You install and manage most components in each resource location. The exceptions are the Citrix Cloud Connectors. You install the Cloud Connectors. Citrix manages the Cloud Connectors.

Citrix Workspace app provides users with secure, self-service access to documents, applications, and desktops from any device, including smartphones, tablets, and PCs. Citrix Workspace app provides on-demand access to Windows, web, and Software as a Service (SaaS) applications. For devices that cannot install Citrix Workspace app software, Citrix Workspace app for HTML5 provides a connection through a HTML5-compatible web browser. The Controller’s services communicate through the Cloud Connectors in each resource location to: This includes managing the state of desktops, starting and stopping them based on demand and administrative configuration. A deployment also uses a configuration logging database, plus a monitoring database used by Director. Azure SQL (PaaS) Database is not supported. The customer administrator does not need to configure or manage anything with licensing. All of that work is done automatically in Citrix Cloud. Studio launches when you select Manage in the Citrix Cloud console. Displays include: It offers several similar features to Citrix Workspace, including subscriber access to apps and desktops, authentication, and other subscriber data that ensures consistent experience across devices. Having local stores can help deliver apps and desktops during network outages. The Local Host Cache feature requires a customer-managed StoreFront in each resource location (zone). The Citrix Gateway or VPX virtual appliance is an SSL VPN appliance deployed in the DMZ. It provides a single secure point of access through the corporate firewall. You manage these resources from Citrix Cloud. Resource locations contain different resources depending on which Citrix Cloud services you’re using and the services you want to provide to your users. A Cloud Connector is the communications channel between the components in the Citrix Cloud and components in the resource location.

In the resource location, the Cloud Connector acts as a proxy for the Delivery Controller in Citrix Cloud. Citrix then manages and updates the Cloud Connectors automatically. The VDA registers with a Cloud Connector. After registration, connections are brokered from those resources to users. VDAs establish and manage the connection between the machine and the user device, and apply policies that are configured for the session. The broker agent hosts multiple plug-ins and collects real-time data. VDAs for Windows desktop operating systems allow only one user to connect to the desktop at a time. Linux VDAs are also available. MCS creates copies of a master image to create and provision VMs. Citrix Provisioning doesn’t require a hypervisor, so you can provision physical machines. The Kerberos infrastructure in Active Directory is used to guarantee the authenticity and confidentiality of communications with Citrix Cloud. Connection specifications include: You can also install applications on the master image, if you want them to appear on all machines created from that image and don’t want to virtualize them. Then, you create a catalog using a Citrix tool (MCS or Citrix Provisioning) or your own tools. With Citrix tools, the catalog creation process provisions identical VMs from that image. Alternatively, you can specify users through the Citrix Cloud console. Alternatively, you can specify applications through the Citrix Cloud console. This information can be helpful in hybrid deployments. That summary guides you through the major steps in the process, and provides links to detailed descriptions.

When the machine restarts, verify that the Citrix Desktop Service starts or restarts. Note: Uninstalling the third party software might not revert the registry value to 1. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it. In addition to changing settings specified when creating the group, you can configure other settings that are not available when you create a delivery group. Some tasks span more than one category. For example, “Prevent users from connecting to machines” is described in the machines category, but it also affects users. If you can’t find a task in one category, check a related category. For details, see Delegated administration. Or, click OK to apply changes and close the window. These URLs are used by the Citrix Workspace app, which is installed on each machine in the delivery group. Or, click OK to apply changes and close the window. This process tells the console about what needs upgrading in the delivery group. For more information, see the upgrade documentation. The Upgrade Delivery Group action appears only if upgraded VDAs are detected. You can then cancel the upgrade, resolve the machine issues, and then start the upgrade again.

This temporary assignment enables the machine to be assigned to a user later. Priority determines the machine’s assigned delivery group when it registers with the system or when a user needs a machine assignment. The lower the value, the higher the priority. If a Remote PC Access machine catalog has multiple delivery group assignments, the software selects the match with the highest priority. Use the PowerShell SDK to set this priority value. Machine accounts or Organizational Units added to the catalog later can be added to the delivery group. This association can be switched off or on. To remove an association, click Remove Association. Or, click OK to apply changes and close the window. The default level is 128-bit. The level can be changed using the SDK.

Therefore, that machine is available for assignment to another delivery group. To temporarily stop users from connecting to a machine while you are removing it, put the machine into maintenance mode before shutting it down. Consider reimaging the machine.

For details, see Delegated administration. Then define the Citrix Gateway site, and add, edit, or remove the SmartAccess policy expressions for the allowed user access scenarios. For details, see the Citrix Gateway documentation. Or, click OK to apply changes and close the window. Access policies are applied to delivery groups to refine connections. For example, you can restrict machine access to a subset of users, and you can specify allowed user devices. Exclusion filters further refine access policies. For example, for security, you can deny access to a subset of users or devices. By default, exclusion filters are disabled. You might do this before applying patches or using management tools. Current connections remain connected until they disconnect or log off. Select a machine, and then click Turn On Maintenance Mode in the Actions pane. Maintenance mode is on when any of the following occur: The Remote Host Configuration User Logon Mode setting is either Allow reconnections, but prevent new logons or Allow reconnections, but prevent new logons until the server is restarted. If the operating system cannot comply, the machine remains in its current state. If Windows attempts to install updates during the shutdown, there is a risk that the machine is powered off before the updates finish. See the Microsoft policy documentation for details. You can create one or more schedules for a delivery group. A schedule can affect either: The machines are identified by a tag that you apply to the machine. This is called a tag restriction, because the tag restricts an action to only items that have the tag. You want every machine restarted once every week, and you want the machines used by the accounting team restarted daily. To accomplish this, set up one schedule for all machines, and another schedule for only the machines in accounting. The duration is either “start all affected machines at the same time” or an interval it takes to restart all affected machines.

Disabling a schedule can be helpful when testing, during special intervals, or when preparing schedules before you need them. In the example above, both schedules affect the accounting machines. Those machines might be restarted twice on Sunday. The scheduling code is designed to avoid restarting the same machine more often than intended, but it cannot be guaranteed. In the example, the weekly schedule that affects all machines might initiate restarts faster than the daily schedule for accounting machines, depending on the duration specified for each. Disabling a schedule can be helpful when testing, during special intervals, or when preparing schedules before you need them. In the example above, each of the machines used by the accounting team has a tag applied. For details, see Tags. If the tag does not exist, click Create and then specify the name for the tag. After the tag is created, enable the check box next to the newly created tag name. An internal algorithm determines when each machine is restarted during that interval. By default, no message is displayed. By default, the message is not repeated. There is no default text. For example: “Warning: Your computer is automatically restarted in %m% minutes.” The value decrements by five minutes in each repeated message. Unless you chose to restart all machines at the same time, the message displays on each machine at the appropriate time before the restart, calculated by the internal algorithm. To disable the schedule, clear the check box. Or, click OK to apply changes and close the window. Update the schedule configuration, using the guidance in Create a restart schedule. Select or clear the Enable restart schedule check box. Confirm the removal. Removing a schedule does not affect any tags applied to machines in the affected machines. This can have unintended results. A site database outage occurs one hour before a scheduled restart begins (02:00). The outage lasts six hours (until 08:00).
