Hello - we have 100+ Win2K8 R2 DC's deployed, running native mode ... noticed even the PDC Emulator has "IsDomainMaster" registry key set to "blank". The MaintServerList is set to Auto on all DCs. This is the default, we did not make any changes, however we do have many clients (member servers and wrkst's) reporting they are now the master.
Q1: Should we adjust our Win2K8 R2 DC's to IsDomainMaster=Yes, MaintServerList=Yes ... also should this be on all DCs, on the PDC Emulator only, or only on 1 DC on each subnet. (I've seen multiple answers for all 3 options).
Q2: Could change all clients (servers/wrksts) to be No,No on both reg keys, but is this safe to do without changing any of the DC's (in Q1).
Thanks.
