I am running a centralized WSUS network over a Windows 2000 Server environment. I have a master WSUS server and six WSUS acting as replicas. Six of the seven servers were previously running SUS; I installed MSDE plus the security patch and then decomissioned SUS and put WSUS on port 80. All computers in the specific GPO I set up started reporting in within 2 days. However, I have a dilemma with the seventh replica server. This server was running SUS but it was uninstalled before WSUS was installed. WSUS set up successfully, it syncs successfully, but out of 40 or so computers, only two reported in over a span of two months. During that time, I checked certain computers to make sure they were getting the GPO (Win Update screen is grayed out with my GPO settings shown underneath but grayed out), i forced the GPO using secedit, and I put a script in the computer OU's startup to register related dlls and reauthorize or redirect old SUS clients to the new WSUS server ( i got it from this site), i ran wuauclt.exe commands on certain computers but all with no effect. I disabled the Software Update Services service thinking that was interfering with something (Windows Software Update Services is running on Auto, MSSQLWSUS$ instance is running), but the other servers were running this unneccessary service without issue. The GPO is exactly the same for each site.
Again, 2 computers checked in successfully, but I'm missing a good 30 computers. About 5% of the PCs may be cloned and I know about the SUS IDs causing issues, but the rest should be checking in. I think I read something recently about uninstalling an instance of SQL screwing something up but I dont know if it applies here. The only errors recorded in the Event Viewer are related to the WUSync Service not finding a SUS Server (this is the now useless Software Update Server service from SUS) but this service has been disabled on each server with no ill effect on any.
What am i missing?
