Hi, I recently set at a new Server 2003 and installed WSUS 3.0 and pre-requisites. The system was running well until I promoted the server to a Domain Controller and since then I am unable to connect to the WSUS server either from a client machine nor from the WSUS admin console. The IIS , Squid and WSUS services are all running but the system does not see the WSUS server. I get an erroe in the Update Services console that states "An erroroccured trying to connect the WSUS server. This error can happen for a number of reasons. Check connectivity with the server. Please contact your network administrator if the problem persists."

Check with tcpview (start on the serverside) if the server is still listening for incoming connections on the configured port.for wsus. Also look into the system and application eventlog for irregularities.

As a rule this problem results from permissions being changed by promoting to be a domain controller. The local accounts that were used to set up WSUS do not exist after DCPromo runs. I have heard of different solutions such as un-installing WSUS and re-installing or checking all related services and WSUS directories to see that proper permissions are set, but that can be difficult to locate.

When I try to uninstall WSUS I get a dialog stating "Setup Not Completed! The Windows Server Update Services 3.0 was not removed successfully because an error occured."

Though I haven't tried it, I have seen suggestions with this issue to manually delete the WSUS folder and run the Windows "Installer Clean Up Utility"

I found this clue on a Google search and this allowed me to uninstall WSUS. By setting the following registry key to 0 I was able to uninstall.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Update Services\Server\Setup]
"wYukonInstalled"=dword:00000001
