Cannot Discover Servers in Citrix Farm

IT Problem

When you install an additional server to your citrix farm and run the “Run Discovery” you see the screen below.
You will see no farm properties or citrix servers as the presentation server discovery did not correctley discover your new citrix server.

Cannot autodiscover citrix farm

Basically, you can discover only the local server, it does not discover the farms settings or any additional servers.

IT Solution

This is down to Citrix xen app/presentation servers not registering DLLs correctly when it installs.

These are the DLLS that need to be registered again, ive created a batch file to do this for you here.

If you do not want to run the reg file copy and past the commands below individually.

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm /codebase "C:\Program Files\Common Files\Citrix\Presentation Server - Administration Snap-in\PSE.Core.dll"

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm /codebase "C:\Program Files\Common Files\citrix\Access Management Console - Diagnostics\CdfExtension.dll"

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm /codebase "C:\Program Files\Common Files\citrix\Access Management Console - Dashboard Watcher\DWExtension.dll"

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm /codebase "C:\Program Files\Common Files\citrix\Access Management Console - Knowledge Base\KnowledgeBaseExtension.dll"

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm /codebase "C:\Program Files\Common Files\citrix\Access Management Console - Hotfix Management\HotfixExtension.dll"

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm /codebase "C:\Program Files\Common Files\citrix\Access Management Console - Legacy Tools\MMCPlugIns\LegacyToolsExt\CMCLaunchExtension.dll"

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm /codebase "C:\Program Files\Common Files\citrix\Access Management Console - Report Center\ReportCentreExtension.dll"

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm /codebase "C:\Program Files\Common Files\citrix\License Server - Administration Snap-in\LicensingExtension.dll"
