Not able to login to domain

anishuthuman
hi,

i am not able to login to domain from a windows xp professional client which is a member of the domain.Only 1 DC is in my network .IP ADDRESS ,SM,DEFAULT GATEWAY ,DNS,all are perfect.Earlier it was logging to domain.But now from last week onwards,not able to login to domain..

The error msg is

"Windows cannot connect to the domain either because the domain controller is down or otherwise unavailable, or because your computer account was not found. Please try again later. If this message continues to appear contact your System Administrator for assistance"

This client was logging with the username and password of a domain account which is using the same logon credentials in another client pc which is a member of the same domain.And also earlier, the another pc and this problem pc computer name was same named as "bala".

I changed the computer name of another pc to "bala1" and the problem computer is now "bala" and was able to login to domain successfully before last week .Later it is not able to login to domain..

Please give me a solution to this..

THANKS IN ADVANCE...

    Sounds like a domain controller problem, when you changed the name of the other computer from bala to bala1 did you assign login policies for the new username from your domain server?

    Earlier, this problem pc was not connected to the network.it was named as bala.when it is connected to the network and made member of the domain ,another computer named bala was found ..so computer name conflict occured.

    so i changed that another computer name to bala1

    and no login policies is given to the username..it is not the new user..bt using login credentials as same as that used in bala1 pc

    A Windows XP Client Cannot Log On to a Windows NT 4.0 Domain

    Windows cannot connect to the domain either because the domain controller is down or otherwise unavailable or because your computer account was not found.

    To resolve this issue:
    Click Start, and then click Control Panel.
    If you are using Classic view in Control Panel, double-click Administrative Tools, and then double-click Local Security Policy.

    If you are using Category view in Control Panel, click Performance and Maintenance, click Administrative Tools, and then double-click Local Security Policy.
    Under the Local Policies\Security Options node, double-click the Domain Member:Digitally encrypt or sign secure channel data (always) policy to open it.
    Click Disabled, and then click OK.
