Citrix XenApp Discovery Process Error

Citrix XenApp Discovery Process Error

ENVIRONMENT

XenApp Platinum 6.0, Windows Server 2008 R2

PROBLEM

After installing XenApp you run Discovery and receive the following error message: “Errors occurred when using Servername in the discovery process.”

Double-clicking the error message to see the error details reveals the following:

“An unexpected error occurred. Check that the server name is correct, that the server is on, that Citrix Presentation Server is installed on this server, and that the Citrix MFCOM Service is running.”

RESOLUTION

I followed the instructions on the Citrix forum to Enable Network COM+ access, and tried to run the discovery process but again received the same error message.

I realized that XenApp had been installed on the system with a local admin account, but the server was recently joined to a domain. I then un-installed XenApp, rebooted the server, then re-installed XenApp using an admin account that was part of the domain. (Citrix recommends that if you un-install XenApp, that you do not install it again until you have a freshly imaged server. This was in a test environment so I ignored these instructions, but did not have any problem after re-installing). After installing XenApp with the domain administrator account I ran discovery again the process completed successfully.

Note: As I later learned, XenApp 6.0 differs from 5.0 in that you do not need to pre-install the Windows roles, the installation will take care of that for you. If you are installing XenApp 6.0 on Windows Server 2008 R2 for the first time, you should be able to run the Citrix installation with out pre-installing the roles as you would with 5.0
