I have a single 2003 domain with 3 primary DNS servers that are also DC’s. Replication between them seems to be fine. However an intermittent problem occurrs where a name is not resolved. When i open DNS and look at the Forward Lookup Zone i see the following: yourdomain.com —>_msdcs —>_sites —>_tcp —>_udp —>… The forward lookup zone is identical on all 3 DNS servers. There is no _msdcs.yourdomain.com above yourdomain.com The _msdcs below yourdomain.com is not a delegation (not greyed). How do I go about getting the _msdcs.yourdomain.com zone back?? Should the forward lookup zone look like this: _msdcs.yourdomain.com yourdomain.com —>_msdcs —>_sites —>_tcp —>_udp —>… I don’t quite understand this whole _msdcs thing.
