I was planning to demote a Win2k8R2 server from the domain (single forest). I decided that I would simply take the server down and see what problems might arise or what implications if any it would cause. I did have a few users static IP using it as DNS.
I'm going to assume it was offline too long. I didn't event think about it. I booted it back up and have been having strange behavior throughout the network since.
The gp_updates for WSUS are not running. If I type gpudate /force from my machine I get the 1058 event so I know I am having issues with that. Probably replication issues as well.
Can I simply demote the server in my current state? Probably not. I see in a previous post the recommended the metadata cleanup but the server is back online. What advice can you give me to get out of this predicament?
Fortunately, it was NOT the FSMO but it was running DNS and GC.
