The Citrix Broker Service cannot find any available virtual machines. Check your hypervisor console to ensure the power action takes place. If this does not take place, additional troubleshooting will be required to address this.
Citrix recommends creating a schedule to restart Virtual Machines during an off-peak time of possible, which will clear the WillShutdownAfterUs e flag.
Desktops will also reach this state when placed into maintenance mode while a session is active, and logged off while still in maintenance mode. Open a ticket online for technical assistance with troubleshooting, break-fix requests, and other product issues.

Had to change a registry setting to Seriously what the hell is this and why do you need to do this? Is it documented anywhere? Came across this issue today. We have this problem about once a month, so far no solution found. Rebooting the system works, but just as workaround because the problem would eventually arise again. Today we had this issue again. VDAs can becomes stuck in the "initializing" state of registration process. The issue occurs after the Citrix Desktop Service is running for several days without being restarted.

Citrix Troubleshooting 101: Frequently Asked Questions

Is there Any solution or answer to this error message?Citrix Virtual Apps and Desktops deployments are performance sensitive. There are many components both datacenter-side and client-side which must be optimally performing together to deliver a consistent and performing virtualized apps and desktops solution. With many different components in play, it can often be a challenging task for a Citrix administrator to determine the impact or cause of a Citrix related problem.
Citrix troubleshooting nevertheless becomes challenging. The webinar was hugely popular simply because as mentioned, Citrix administrators want to be able to quickly and more efficiently diagnose issues within the environment.
Citrix issues ultimately result in lost productivity and company revenue. The severity of lost productivity and revenue is mainly determined by the time it takes to resolve an issue. For an administrator to be successful in Citrix troubleshooting, the process of elimination is key. The process of elimination can be applied to three particular troubleshooting tactics that were highlighted in the webinar.
Following these tactics will help you to become more efficient at diagnosing Citrix problems:.Citrix HDX RealTime Optimization Pack for Skype for Business – User Experience Demo
We compiled the dozens of participant questions into three groups below: Citrix Troubleshooting, Citrix Optimization and Citrix Monitoring.
George Spiers provided all answers based on his real-world Citrix consulting projects. We encourage you to save and regularly reference this Citrix troubleshooting guide for any issue you may encounter.
Citrix Troubleshooting. You may want to consider logon simulators and full session simulators available in the market. See the following links:. That may involve you killing hung processes. I can accept 40 seconds or less, but 30 seconds downwards is the real goal. It can actually be beneficial to run both, as they work together well.
Profile Management captures and roams the user profile between desktop or virtual application sessions. One of the reasons for this could be that you have not optimized the Windows Server image? Default settings in the operating system are not the best. I would run through a process of elimination to see if the issue only happens at a specific user location, with specific endpoint clients, with specific Receiver versions and so on. Have your network team run tests on the networking devices that are client-side to see if there is any packet loss.
I only recommend rebooting XenServer hypervisors either during disaster recovery testing phases, or when applying hotfixes to XenServer.This article covers troubleshooting issues encountered when users attempt and fail to connect to XenDesktop virtual desktops.
When the user requests a connection to a virtual desktop, a number of tests are performed and checks made to select the correct virtual desktop to which they must be connected. If one or more of these tests fails in some way, the desktop launch is refused and the user is informed that the resource is unavailable. An event log message is also produced on the DDC machine describing why the launch was refused, and this article is to aid troubleshooting these situations.
No suitable desktop machine was found which was ready to satisfy the failing launch. This might be because of some machines being marked as in maintenance mode, or simply running out of desktop machines. Either add more desktop machines to the site using the Desktop Studio console, or remove the maintenance mode setting on one or more of the relevant desktops or machines using the Desktop Studio console or the Broker PowerShell SDK. The agent software running on the select desktop machine actively refused a request to make the machine ready to accept a connection from the user.
If registry-based controller discovery is in use, which is the default mechanism, ensure that the desktop machine in question has been configured with a list of controllers that includes the controller that attempted the failed launch.
Examine the event log on the desktop machine in question for further error indications, and if necessary use logging of the workstation agent service to capture traces of the launch sequence actions. The desktop whose launch failed was already running a connected session for the user and active session reconnected has been configured to be disabled. If active session reconnection must be allowed, change the value of the DisableActiveSessionReconnect registry entry.
The desktop or machine selected to be used for the launch is currently flagged as being in maintenance mode. This might be because the user already has a session on that machine, which prevents the system choosing to use another machine for that user, or the machine might be permanently assigned to the user.
Either remove the maintenance mode setting on the desktop or machine using the Desktop Studio console or the Broker PowerShell SDK, or end the running session on the desktop or remove the permanent assignment. The protocol requested to be used for the failing launch, for example HDX or RDP, is not supported to be used with the selected desktop machine. VM-Hosted application, which defines the failing launch application, is marked as disabled.
The desktop or machine selected to be used for the launch is already running a session, and this session is not suitable to be used in the failing launch circumstances. This might occur if a desktop has been permanently assigned to a user, but then a different user logs on to the machine, for example through the machine console. End the running session on the desktop or remove the permanent assignment.
The desktop group, which would provide the desktop for the failing launch is marked as disabled or has been deleted. If the desktops available to the user are re-evaluated, for example, the user logging on to Web Interface again, this resource would not be offered to the user. If the launch failure cannot be categorized to a particular failure reason, one of these events occurs.
The behavior occurs when XenDesktop fails to start the required machine for the requested session. If the machine is running on a hypervisor, this might occur when the hypervisor is Off, the hypervisor does not have enough resources to launch the virtual machine for example out of memory or VDA is in maintenance mode. If the preceding descriptions of the event circumstances do not provide sufficient clues to determine the problem, logging of the Citrix Broker Service must be used to capture traces of the launch sequence actions.
So, collect CDF tracing, and select the following modules to be traced:. Open a ticket online for technical assistance with troubleshooting, break-fix requests, and other product issues.
