Having some DNS problems perhaps someone can discern more from this dcdiag result:
Domain Controller Diagnosis
Performing initial setup:
* Verifying that the local machine dc01, is a DC.
* Connecting to directory service on server dc01.
* Collecting site info.
* Identifying all servers.
* Identifying all NC cross-refs.
* Found 4 DC(s). Testing 1 of them.
Done gathering initial info.
Doing initial required tests
Testing server: NY\dc01
Starting test: Connectivity
* Active Directory LDAP Services Check
The host 35d0baa2-268b-4290-b4d8-5a
2336c04e90
._msdcs.ec
o.ecomarke
ts.com could not be resolved to an
IP address. Check the DNS server, DHCP, server name, etc
Although the Guid DNS name
(35d0baa2-268b-4290-b4d8-5
a2336c04e9
0._msdcs.e
co.ecomark
ets.com)
couldn't be resolved, the server name
(dc01.eco.ecomarkets.com) resolved to the IP address
(192.168.11.17) and was pingable. Check that the IP address is
registered correctly with the DNS server.
