I have a fairly windows 2008R2 physical server, at one point it was in a sub office running as a DC for that office It was one of many DC's in our domain which is spread across multiple offices. We closed the office recently so I demoted it back to being a member server before hand. It has not been used since.
As the server it fairly new I was looking to redeploy it to another sub office to replace an old server, My question is - Is it ok to just rename the server / Change the IP address and repromote it back to a DC or should I reinstall windows on it first before doing this?
