Error in Accessing Primary Domain Controller from Backup Domain Controller

Hi,

We have Windows 2003 server based network of around 10 computers. We have
one computer desingtated as Backup Domain Controller.

All of a sudden, we are not able to access the primary domain controls from
the backup domain machine. The error is following:
+-----------------------------------------------------
Logon Failure: The target account name is incorrect.
-----------------------------------------------------+

demoting this computer to a regular computer in the network does not work.
While dcpromo wizard is on, we get teh same error and the wizard ends
prematurely.

We can access all other computers from this computer in the network. We have
DHCP based network and no static IPs are given to any computer. The backup
domain controller has global catalog and can perform tasks of
authentication, user logns etc.

How to solve this issue? Any help would be really useful.

I have to assume there is some type of dns error going on here. Do both
machines point to the same dns server? Can the faulty dc ping the other dc?
Is there a firewall of any kind between the two? You should run diagnostics
on this machine to determine more of what is going on. Worst case scenario
you can demote this machine via dcpromo /forceremoval but then you have to
go back and clean up the metadata. Before you take that step you should see
what is causing this error , otherwise you may end up back in the same
situation even if you demote and promote out of the current issue.

Run diagnostics against your Active Directory domain.

If you don't have the tools installed, install them from your server install
disk.
d:\support\tools\setup.exe

Run dcdiag and netdiag in verbose mode.

If you download a gui script I wrote it should be simple to set and run. It
also has the option to run individual tests without having to learn all the
switch options. The details will be output in notepad text files that pop
up automagically.

The script is located in the download section on my website at
http://pbbergs.dynu.com/windows

Just select both dcdiag and netdiag make sure verbose is set. (Leave the
default settings for dcdiag as set when selected)

When complete search for fail, error and warning messages.
