Missing Computers in the WSUS Console

One of the more frustrating problems I have run into when deploying WSUS is when computers simply do not show up in the console. Here is the most common solution to this problem.

One of the most frustrating problems I have run into when installing WSUS was an installation in which most of the computers in the organization were not showing up in the WSUS console. My GPO was setup correctly and WSUS was running, but most of the computers were simply just not showing up.

After some digging here are the results I came up with. The IT Administrator who originally setup the network did so through ghost imaging. In doing that, sysprepping his original source image wasn’t in his list of steps. That being the case, some of the registry keys specific to Windows Update that sysprep clears were inherently not cleared properly.

Fixing this issue is a pretty simple registry edit for each computer. First, make sure that the Automatic Update service is stopped. Open up regedit, and browse to HKLMSoftwareMicrosoftWindowsCurrentVersionWindowsUpdate. From here, delete the PingID, AccountDomainSid, and SusClientId entires. After doing this, start the Automatic Update service again, and at a command prompt, type “wuauclt.exe /resetauthorization /detectnow”. This should make the computer show itself in the WSUS console
