So I have a bit of a weird thing here. I was testing Forefront with MOM 2005 and WSUS and ran into a problem. One of the computers I was testing with had to be re-imaged due to a failed SP update. Because of this, I had to delete it from the domain, and not unjoin it.
When I re-imaged the machine and joined it to the domain, I used the same hostname (we use the service tag as the hostname). Apparently, WSUS did not like this as it thought it was already current with updates. I changed the hostname in order for WSUS to push the updates to the client (which also included FF and MOM 2005) and everything seemed fine. That is, until I changed the hostname back to our standard.
The hostname change does not reflect in the MOM console, and I can't seem to get it to. I've tried rediscovering attributes, I tried unjoining and rejoining the domain. Everything short of uninstalling the agent and reinstalling it. Is that really the route I have to go, when I need to rename a computer?
