Question : Problem: WSUS not showing some of our Servers

We have WSUS running on a Microsoft Windows Server 2003 R2, Datacenter x64 Edition SP VM server.  We have 2 Citrix servers and 4 VM servers that are not showing up in the "All Computers" area , or anywhere, of WSUS.  I have looked at the Windowsupdate.log of the 2 Citrix servers and it shows that the Windows Update Agent is running.

Can you tell me how to get these 6 servers to show up in the WSUS?

Answer : Problem: WSUS not showing some of our Servers

The reboot or restart will be on the server/workstation that does not display in SUS.  Here is the MS article that has greater detail.
