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.
