The trust relationship workstation primary domain failed.
A list of idea's and fixes I found while searching for the " The trust relationship between this workstation and the primary domain failed " problem are below.
What was found:
When your Vista is connected to the domain network and the user login was successful according to the event log but the Vista computer reported "The trust relationship between this workstation and the primary domain failed."
At that point Vista stops and gives no other options.
Now to discover the fix for this specific issue.
I'll follow up with what actually works today.

Bruce offers this fix:
Directory Users and Computers you:
right click the Vista Computer's account
select Reset Account
you have broken the trust relationship with the Vista Computer and it will
have to be joined to the domain again.
1. Login to the Vista computer using the local, administrative user account
that was created when Vista was installed
2. click Start, right click Computer, select Properties
3. click Advanced system settings in the left (Tasks) pane; click Continue
4. select the Computer Name tab; click Change...
5. select the Workgroup radio button; key any character string (e.g.
workgroup); click OK
6. key something (anything) in the user name and password boxes - you have
to key something, but it doesn't matter what; click OK
7. you should get the Welcome to the ... workgroup. message box; click OK
8. restart the computer
9. on the domain controller, reset the computer account
10. login to the Vista computer using the local administrative user account
(same as step 1)
11. join the computer to the domain again (same idea as steps 2 through 6,
except select the Domain radio button and supply appropriate domain
credentials when prompted
If there is still a problem, then I suggest do steps 1 through 8, then
delete the computer account from the domain, create a new computer account
with the same name, then join the computer to the domain again (steps 10 and
One major problem I found with the above but has a simple fast way of resolving the issue.
If your customer doesn't remember even the login name (username)
then start Vista in Safe Mode Command Prompt.
Type: net user
That will display the user accounts in the machine.
You can also check to see if the admin password has been set to blank by trying to change it.
The command line to change your password goes like this.
First we need to set the Admin account Active.
net user administrator active
net user administrator password
I'll update this when I get back to the Vista Machine.
But you should be able to see your usernames which might give you a clue to the logins.
