cant log on

I upgraded a Windows XP Pro workstation on a Domain to the Vista 2 Beta, and it worked fine. Then I did the next computer on the domain, and it got as far as log in to Windows Vista, and looked like it was OK. When I went to log in as the user. It started logging in, and then said closing your desktop. I tried the user, the administrator and any other password I could use. All of them did the same thing. I tried the DVD to boot and use the auto repair, and it told me it could not fix it. I am now stuck, as the is past the auto rollback function, and when I try "log onto earier windows version" it stalls. I called support, and they said to check the website. Any ideas?

Why, again why would you install "BETA" version OS as an upgrade on what seems to be a production computer (on a domain yet) despite the numerous admonitions and recommendations not to so - and without thoroughly evaluating the installation proceed with another beta installation. Note the many, many. many posts regarding similar problems.
