Computers Not Showing in WSUS
Posted on 2010-09-10
Got a Windows Server 2003-based Active Directory network with approximately 150 Windows XP Professional Service Pack 3 workstations. I am attempting to implement a WSUS server for our organization.
I have installed WSUS, configured it, and set the group policy (for the entire domain) to point workstations to the server. Thus far, only about 100 of the 150 workstations have appeared in the WSUS management console. The other 50 or so workstations are not showing up.
In an effort to troubleshoot this problem, I have done the following:
1. I have run the "wuauclt.exe /detectnow" and "wuauclt.exe /resetauthorization /detectnow" commands. Neither produces any effect.
2. I have run the WSUS client diagnostic tool. On some workstations, it reports that the UseWUServer value is missing from the registry. However, when I create that registry value (in HKLM\Software\Policies\Microsoft\Wiindows\WindowsUpdate\AU" and set it to a value of 1, the diag tool runs successfully and reports no errors, but the computer still never appears in the server console.
3. I have used the script, posted in other question threads here on EE, to reset the SID and registry key values, and then re-run the "wuauclt.exe /resetauthorization /detectnow" command. Still no change.
4. I have checked the IIS server settings and have verified that the WSUS web site is on the default of port 80 and, therefore, the server address I used in Group Policy is correct.
If anyone could offer any additional suggestions, they would be most appreciated. Thanks!
