We have to request that someone manually registers the SRV records for our AD domain. Now we are upgrading to 2008 R2 from 2003 R2 and we will demote the 2 olds ones and bring in 2 new. My question is, is it a problem if we have both the old PDC and the new PDC registered as PDCwith the SRV record in the DNS at some period of time when we migrate the domain? There will be difficult to switch at an exact time. I mean will the clients who look for the PDC just pass on over to the one who is actually the PDC at the time and ignore the false PDC record?
