How to join a remote domain over IPSec?

We have 2 offices, the main office network details below:
ADSL Modem(Static IP) -> FireWall(192.168.100.1) -> Internal network(192.168.100.2-254)
The remote office network details below:
ADSL Modem(Static IP) -> FireWall(192.168.200.1) -> Internal network(192.168.200.2-254)

The VPN(IPSec) is established between these two sites thought the FireWall, also all IP addresses fromboth sites are dynamic assigned by the firewall. The PCs in both sites can ping each only by IP Addresses but not PC names.
When I try to join in the domain, it said "A domain controller for the domain could not be contacted". I think that's why I cannot join the remote office PCs to main office domain where has one DC and DNS server.

I need a solution to solve this problem. Anyone got any ideas?

Thanks a lot

IT has relationship with what brand of firewall you used, some firewall could do it like sonicwall.
In Active Driectly clients find domain controllers (and other info) using DNS, and it sounds like your DNS setup isn't quite working. Try setting the dns server in all the workstations to the one dns server in the other location.  Once you are able to ping by DNS name you'll be able to join the domain.

I created a couple of entries in LMHOSTs file, so I can join in the remoted domain now. Thanks lrmoore.
Also I think if I setup WINS server which would be easier to handle all my pcs. Thanks gbirkemeier.
