I have a SBS 2011 Standard called server1 where ipconfig /displaydns reports 'Name does not exist' for
_ldap._tcp.server1.mydomain.com
_ldap._tcp.default-first-site-name._sites.server1.mydomain.com
_gc._tcp.server1.mydomain.com
_gc._tcp.default-first-site-name._sites.server1.mydomain.com
It seems like the queries fail because DNS can't resolve *._tcp.server1.mydomain.com
But when I take a Wireshark trace on the nework interface I see that client is doing DNS queries for *._tcp.default-first-site-name._sites.mydomain.com
The DNS has a forward lookup zone mydomain.com with entires for
_ldap._tcp.mydomain.com
_ldap._tcp.default-first-site-name._sites.mydomain.com
_gc._tcp.mydomain.com
_gc._tcp.default-first-site-name._sites.mydomain.com
When I run dcdiag /test:dns I get no errors. At the same time clients has severe connectivity problems which seems related to DNS queries which fail. What is needed so that I don't get these unresolved names in DNS ?
