Hi

I came accross a problem today, when I tried to view a certain PC on the domain I got the following error "Trust Relationship between this workstation and the Domain Controller Failed".  So I deleated the computer account from the domain server and added it back in, still the same problem.  I googled on the problem and I came accross a soloution where you remove the PC from the domain and added it to a workgroup, then restart and then add it back to the domain.  So I tried this, was able to add the PC fine to the workgroup, however when I try and add the PC back to the domain I get the following problem:

I right-click on my computer and click on the network identification tab, I then go to the properties box, change the 'member of' to the domain option and type in the domain in the corresponding box.  When I click ok it asks me to put in a username/password that has permission to join the domain, when I enter in the username/password I get the following error "The credentials supplied conflict with a existing set of credentials"  even though it is a brand new username/password that has all the necessary permissions.

Any ideas?

Hi garethcummings,
> credentials supplied conflict
To resolve this problem, blank out the Username key in the registry for HKEY_CURRENT_USER\Network:
Log on as an administrator at any workstation.
Click Start, click Run, type regedt32, and then click OK.
Select HKEY_USERS, but do not open.
From the Registry menu, click Load Hive.
This will bring up a Load Hive dialog box. Locate the Ntuser.dat file for the user with the errors. Select the Ntuser.dat and click Open. You may enter any string for the Key Name. Use TEST for ease of use pertaining to the remainder of this article.
Locate the Username value under the following key in the registry:
HKEY_USERS\TEST\Network\Username

Delete the string for Username (leaving it blank is sufficient).
Select the TEST hive that you previously loaded, click the Registry menu, and then click Unload Hive.
Quit Registry Editor.


Cheers!
