I had a network with two file servers. Hyper-V1 which hosted Server1 and Exchange1; Hyper-V2 hosted Server2 and Exchange2. Exchange was installed on Exchange1, but not completely configured and operating. The hard drive with the virtual disks for Server1 and Exchange1 has failed completely. The two servers were using DFSR successfully, so the users are able to continue in an almost unaffected manner.
Both server1 and server2 were domain controllers. Server1 held the FSMO roles.
I am in the process of rebuilding Server1 to the same system that existed. While Exchange was not functioning, it was installed, and there are a lot of exchange entries when I open the ADSIedit tool.
What is the best way to clean up server2 of any reference to server1 before I rejoin the new server1 to the domain?
