Director & WinRM : Sometimes size does matter!

Posted Leave a commentPosted in Citrix, Microsoft, Troubleshooting

As you may know, some features of Director rely on WinRM and you have to configure it following this article http://support.citrix.com/article/CTX125243. In large Active Directory environment, the user security token that is used to authenticate the user to the server may be larger than 16 KB. This can occur when a user is a member of many security groups. However, WinRM has a 16 KB size limit for HTTP authorization requests. Therefore, WinRM does not accept HTTP authorization requests that use […]

How to become a myCUGC leader!

Posted Leave a commentPosted in Citrix

Last Wednesday it was the first event of the French Citrix User Group Community. If I trust the different feedbacks, everyone enjoyed and asked for a new one: we are working on it! What I’d like to share here is my experience: becoming a “myCUGC” leader for the French group behind the scenes. We have been talking about creating something in France since almost the beginning of the CUGC program in May 2015. Talking is easy, implementing is another thing! […]

During a site upgrade I forgot to add my admin account in the “Full Administrator” role… Before rolling back to the previous version, I’ve performed some tests and here is the result: Connect to SQL Server Retrieve an account with the correct role through the SQL query: SELECT Administrators.Sid FROM [DAS].[Rights] as Rights, [DAS].[Administrators] as Administrators, [DAS].[Roles] as Roles Where Rights.AdminId = Administrators.Id and Rights.RoleId = Roles.Id and Roles.Name = ‘Full Administrator’ Modify the SID find with the previous query or create a […]

Studio couldn’t be launched if one Delivery Controllers goes down

Posted 3 CommentsPosted in Citrix

A rapid post about a really strange situation I’ve encountered at a customer site. On a XenDesktop 7.5 site with 2 or more delivery controllers we have detected that if one DC goes down, the site administration via Studio or Powershell is not possible from the other Delivery Controllers. Even if I’ve encountered the problem on a XD 7.5, the problem exists in version 7.6. This is due to the status of the Delivery Controller in the site database. In […]

wmiprvse.exe uses a lot of CPU during user logon on a RDS/Citrix box

Posted Leave a commentPosted in Citrix, Troubleshooting

During a loginVSI load testing scenario on physical servers, I’ve encountered a specific problem: around 170 to 180 users (with a 15 second logon rate), the XenApp server stops opening new session because of a CPU outage. After a couple of dozens of minutes, the server was returning to a more expected value (about 60% of CPU usage). After this pause, the server is re-performing well and new sessions could connect without any problem. During this CPU peak period, the […]

Automate Citrix Director 7.x installation and configuration

Posted 1 CommentPosted in Citrix

This article is about creating a silent installation and configuration of a Citrix Director 7.x website. The installation is quite easy (the MSI file is on the x64\DesktopDirector folder of the install media): msiexec /i DesktopDirector.msi  /qn Once this done, you have to configure the Desktop Director in order to connect to your XenDesktop site(s). This is done using the DirectorConfig.exe tool. This tool is, by default, in the c:\inetpub\wwwroot\Director\tools folder and is explained (briefly ) here: http://support.citrix.com/article/CTX137990 The following line will […]
