We have a remote server running 2008 R2 standard that has been connected to an existing domain running at the 2003 functional level
on doing a DCDiag /test:dns the 2 2003 servers report everything is ok, however the 2008 server reports a problem - it cannot find the domain GUID. a bit of digging reveals it finds the first Domain GUID, which happens to be the correct one according to the other 2 servers. The one its looking for is different and is only reported as missing on the 2008 server.
the report looks like this -
Missing SRV record at DNS server 192.168.21.250:
_ldap._tcp.d952a97b-b6fc-4e87-b88e-7e61026aefc6.domains._msdcs.DOMAIN.local
Error:
Missing SRV record at DNS server 192.168.2.4:
_ldap._tcp.d952a97b-b6fc-4e87-b88e-7e61026aefc6.domains._msdcs.DOMAIN.local
the *.21 network is the home network. the *.2 network is the remote network with the server.
the dcdiag tests on the other 2 servers do not report this. Under the _msdcs.domains object in DNS there is one GUID, and the reported missing one is not it.
So is this a problem? it does not appear to be affecting functionality of the domain, but we do see some strange logs from netlogon sometimes, which is how we found it.
and can it be corrected?
