One DC cannot communicate with another DC. Error: "There are currently no logon servers available to service the logon request."

A DC in a remote office cannot communicate with any other computers on its LAN or to the main DC.  When I try to browse to any other computer thru My Network Places or thru Run,\\<computername>, the above error appears.  I'm able to make a PC Anywhere connection to the machine, though.

Additionally, when the computers on the remote subnet try to access the remote DC, they get the same error message.  However, I'm able to browse to any computer on the remote subnet from my computer (which is on the same LAN as the main DC).

When I try to open Active Directory from the remote DC (Users and Computers, Sites and Services, or Domains and Trusts) the error states: "Naming information cannot be located because: No authority can be contacted for authentication.  Contact your system administrator to verify that your domain is properly configured and is currently online."

There are tons of Event log errors on the remote DC from the NTDS KCC stating that the configuration for replication is SMTP, which is not supported for DCs in the same domain.  However, replication is set to IP.  Any ideas or places to start looking would be appreciated.  Thanks!

Is there a trust relationship between the DCs?

Yes there's a trust.  These are both domain controllers for the same domain.  The one in the remote office is unable to authenticate any domain users because it cannot verify them from the main DC.  I don't think it has been getting replication for 4 days.
DNS is configured on the remote DC, yes.  I'm pretty certain its configured correctly because the machine was having no problems as of last week, and nobody has touched it.  The remote computer is the authority for its zone.
