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.
