DNS seems incorrect after promoting 2008 R2 Server and demoted 2003 server as domain controllers
After transferring the FSMO roles to our 2008 R2 server and making it the new PDC. I was unable to get the 2003 server to graciously demote as DC, I then used the dcpromo /forceremoval, since then we are unable to reconnect the 2003 server to the domain, All the workstations can no longer connect to Exchange (also hosted on the PDC at this point), when running a nltest /dclist:domain command the domain cannot be found. I have attached a copy of the dcdiag, any help would be appreciated. dcdiag.txt nltest.txt
