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."
