I have approximately 250 PC's in my network.  A while ago I was able to install WSUS on my network to enable updates to the PC's on my network.  It worked for approximately 150 machines,but not for the rest.  The WSUS console does not show any other machines in the unassigned computers except for the 150 machines.  I have windows update services turned off on my network PC's as I want to determine which updates are installed.  I have been working on this for serveral weeks, but no matter what I do no more that those orignial 150 machines show in the WSUS console and inspections of the other PC's show that updates are not being perfromed.  Can anyone tell me why all the PC's are not updating?

I tried the solution suggested by dstewartjr, but it did not fix the problem.  I do not see anymore PC's in the WSUS console.  I have randomly checked several of the PC's that don't show up, and some of them are doing windows updates, while others are not.  Any other suggestions that might help alleviate this problem?

Are the PC's that arent showing up getting the WSUS gpo?? <<use Rsop.msc to check

Are there any errors in their windowsupdate.log?? <<< post if you are unsure what to look for

I'm with dstewartjr on the duplicate sid concept.

Delete all of the visible computers from WSUS. Don't worry - they will populate with the next frequency interval. On a test computer try running this script:

net stop wuauserv
REG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v AccountDomainSid /f
REG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v PingID /f
REG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v SusClientId /f
net start wuauserv wuauclt /resetauthorization /detectnow
Pause

You should immediately see the machine report to the WSUS as an unassigned computer.

No one else came up with the right solution and this was so unusual that I felt it needed to be documented so someone else would have the answer if they ran into this.
