Problems logging onto an NT4 domain

By christemple ·
I have 4 XP Pro workstations which have been configured to connect to an NT4 domain. The computers have been added to the domain without problems but I am now unable to log onto the domain as a user.
When trying to logon to the domain as administrator, or any other user account, you get an error that the domain controller is unavailable or the computer account could not be found.
When trying to view the computer account from the server you get an error that the PC is not trusted on the domain.
All NT4 workstations will logon without problems but I am getting nowhere with the XP PCs. Any help would be appreciated.

I have had a similar problem. What is happening is that your workstation doesn't have a proper trust relationship with your NT server.

This is what worked for me. Change your workstation from a Domain to a Workgroup. Name the workgroup whatever you want. Restart the computer. Change your workstation back to a Domain, and restart your computer one final time. This establishes a trust relationship between the server and workstation.

Right click my Computer > Properties > Computer Name > Change to change workgroup and domain.

Good Luck!

Unfortunately I have tried this already and had exactly the same problem.

Thanks for trying.

Unfortunately this hasn't resolved the problem. The same error message is given when trying to logon.

Has anything else changed with your domain controller? I had similar problems when I changed the domain controller from an NT Server to a Win2000 Server. By unjoining and rejoining the domain as specified in Answer 1, the new PDC could then properly recognize the XP's. My question is ... how to go through this process without having to re-create the user's profiles since unjoining and re-joing a domain creates a new (empty) profile. Good Luck

The DC has not been altered at all.

Do you know if NT server has to have a particular service pack installed to recognise XP machines ???

The Microsoft KB 318266 describes your problem exactly and lays out the solution.


RESOLUTION
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.
Good Luck
