A domain controller for the domain abc.local could not be contacted

[Chris Hayes]

Greetings,

I am trying to join a computer to my new domain on a Windows Small Business
Server 2003 and keep getting the following error: A domain controller for
the domain abc.local could not be contacted.

After reviewing the error details I feel I'm close to solving the problem
(I'm pretty sure it's the Host (A) record not being set right), I just don't
know where to look to actually fix the problem.

Does anyone have any suggestions on where to look?

Thanks,

Chris

DNS was successfully queried for the service location (SRV) resource record
used to locate a domain controller for domain grendelcompanies.local:

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

The following domain controllers were identified by the query:

grendel.grendelcompanies.local

Common causes of this error include:

- Host (A) records that map the name of the domain controller to its IP
addresses are missing or contain incorrect addresses.

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

I found out where to add the Host (A) record and that didn't fix it... any
other ideas?

Problem found, it was on the client that was trying to attach the Grisoft
firewall was active and preventing the necessary communication.

Sorry for the false alarm... (stupid firewalls).
