Computer account deleted from AD but somehow WDS server still finds it
This is one of those problems I'm sure somone has had and answered but I can't find it on google because it's too hard to describe.
I have a 2 DC 2 file server network with 250ish XP clients. We moved from our old building to our new school recently and took our PCs and servers with us. The new building is a different size and shape so rather than moving PCs room to room we just stacked PCs by model type and filled suites with apropriate numbers of machines.
We deleted all machine accounts from AD and then proceeded to build the machines from WDS on a server 2k3 R2 server with the "For unknown clients notify admin and respond after approval" setting. We named 99% of the machines this way and it was all flawless... except 1 machine.
1 Dell 745 Low profile system does not request admin approval it instead rebuilds from WDS with its old computer name. I've searched AD for objects with the same name looked through all the OUs and there is no entry for this machine in AD but yet WDS is rebuilding it each time...
Where could WDS be finding this computer account info? and how do I kill it?
