We are a small Catholic school. We currently utilize a server running NT 4.0
for user account management along with a filesever running Windows Server
2000.

Following the very same process that I use to join an XP Pro unit to our
network, under the properties for the unit I try to change from a workgroup
to our domain. After entering the domain, the user name (system admin) and
the corresponding password, I get the error message " Logon failure: Unknown
user name or bad password.

If I use the 'network wizard' in the same area, I go through all of the same
steps that I would if joining a WIN XP unit. At the very end of the process
I am receiving the system error: " Your computer could not be joined to the
domain because the following error has occurred: There is no user session
key for the specified logon session.

HELP... HELP PLEASE.

Try creating a new 'test' user on the Vista computer and give that person
admin rights. Now on the NT4 computer, create that same user account.
Restsart Vista computer and see if this new user account works. If not, you
may have an NT4 issue.
 
I'm having the same problem.
Creating another account on the Vista system did not help.
 
Under Local Policies > Security Options

Change the value of "Network Security: LAN Manager authentication level"
from "NTVLM2 responses only" to "LM and NTLM - use NTLMv2 session security
if negotiated"

This worked for me.

you may also need to add the computer to the domain via server
mamager. I had to do both this, and change the auth method mentioned
above to get Vista on to an NT 4 network
