Vbscript: windows 2008 server fails to autologon

Question

I am doing some automation work that requires several reboots. I am trying to allow my server to auto logon with the admin account. I can get it working locally, but when I try to do it as a member of the domain it fails.

It appears to me that it is not even trying to perform the logon. If I put a invalid password into the defaultpassword field (when loging on locally) it will present me with a bad password message, just as if I typed it from the keyboard. If I do the same thing to the domain, it does nothing.

Here is the code I am using and have found ref'd on on several different sites and used:

This code works fine joining to our 2008 DC. What I believe the problem was has to do with some of our security settings and possilby kerberos between a 2008
