Computers disappearing from WSUS

I am using WSUS 3.0 SP1 to distribute updates to my network computers.  It has always worked great, but after installing a new set of Dell Optiplex 755 machines using Sysprep and Ghost, it seems that only one of the computers shows up at a time in WSUS.  Then when the next machine reports its status, it overrides the previous one.  In other words, WSUS seems to think that all the computers are the same machine, and is only keeping the status of one of them active.

I've checked the SIDs and the MAC addresses, they are different on each computer.  How does WSUS keep track of the computers, and differentiate one from another?

I believe each computer account also has a SID that is seperate from the computer SID. You may want to try and rejoin some of the computers to the domain to see if that does not help since that changes the computer account SID. Check out this thread from techexams.net, there is some useful info there.

I am having a simliar problem. Has anyone found an easy solution to this issue? I use Ghost and sysprep. This issue never happened before. But it is now happening with a recent deployment of 700PC's. Only 1 at a time shows up in WSUS console.
I am having an almost identical problem with Optiplex 755s, dployed with WDS on Server 32003 R2. I have three PCs showing up at any given time, and every time one checks in another one disappears.
The PCs all seem to update exactly as they should though.
Anyone made any progress with this?
