Wsus Database only showing 169 computers

[longman111]

I have observed today that I have only 169 computers showing up in the wsus
console. I know I have well over 200. For those computers that are not
showing up, if I force a detection on 1, it will be added to the wsus
console, however when it is added a different computer is removed from the
console, always leaving the total count at 169. This sounds like a database
issue - maybe a size issue - not sure. I am using the Windows Database.
Thoughts?

Most likely your clients were deployed with non-sysprep'd images that have
duplicate client ID's in them that WSUS uses to identify the machine.
You'll need to reset them at the client. See:

Or.... the authoritative source at http://support.microsoft.com/kb/903262

Which is undoubtably more up-to-date than either of the above cited
references. :-)

Thanks guys - figured it out about an hour ago. Wrote a quick script and
fixed about 40 computers. Will speak with the workstation admin tomorrow
about the cloning issue.
