I have a brand new Dell laptop I just took out of the box and tried to join it to my domain.  It gave me an error message stating that it couldn't find the domain name I entered.

Under details it gives me the following info:

-------------------------------------------------------------
DNS was successfully queried for the service location (SRV) resource record used to locate a domain controller for domain "lpgaoffice":

The query was for the SRV record for _ldap._tcp.dc._msdcs.lpgaoffice

The following domain controllers were identified by the query:
antares.lpgaoffice
excelsior.lpgaoffice


However no domain controllers could be contacted.

Common causes of this error include:

- Host (A) or (AAAA) records that map the names of the domain controllers to their IP addresses are missing or contain incorrect addresses.

- Domain controllers registered in DNS are not connected to the network or are not running.
-------------------------------------------------------------

Using a network analyzer, I do see the DNS query going out and coming back, and I see that the response includes the SRV records for both domain controllers, as well as their IP addresses.

From the client, I can reach the domain controllers that were returned by DNS (i.e. antares.lpgaoffice and excelsior.lpgaoffice) and see shared folders on them after I am prompted to authenticate.  In other words, if I go to start > run and type "\\antares.lpgaoffice" I get a list of shared folders on that DC, so I know the client can talk to the DCs.

I'm mystified why I am getting this error since DNS appears to be working properly, and there is connectivity from the client to both DCs.  There are no firewalls between them in the network, the only firewalls are the standard Windows firewall.  I've tried turning those off but that doesn't make any difference.

The client is Windows 7 SP1 and the DCs are Windows 2008 SP1.
