How do you remove multiple domains on a windows 7?

Ok I have searched for hours, we have an interesting problem here, we took our desktops and laptops and removed them off one domain controller to a completely new one. No issues there, worked fine. However now when we boot some of the systems, it by defaults sees the old domain as a domain to log into and we have to hit switch users to see the new domain. (Yes the old DNS is no longer showing, we did the flushdns and registerdns and nbtstat -R already on the systems and no changes or luck on that)

How can remove the old domain from showing up and defaulting to the new domain? This is a huge issue for my boss who is on his laptop with Win 7 64-bit, and using the biometric fingerprint which isn't working because the initial domain that shows is the wrong one and is no longer a member of.

I have searched and found nothing but how to remove a domain which is pretty straight forward.

Try removing the domain, join workgroup, and rejoin domain.

wouldn't this mess up the user profiles that are already in use on this system?

If his profile is part of domain a and you have domain a and domain b on the computer and you remove the computer from the domains to rejoin it to domain a, he will not loose anything. If his profile is a part of domain b and you are getting rid of b to switch to a only, you can use a wonderful tool called user profile wizard http://www.forensit.com/downloads.html

Ok, let me go over what is going on with his PC, it used to be part of Domain A, we changed it to Domain B, updated his profile to Domain B. When he goes to login it is showing both domains A & B, when everyone else is showing only Domain B now.

I do not know if it has anything to do with the biometric fingerprint reader or not. We have narrowed it down to when he swipes his fingerprints, even after removing them and re-enrolling them, it tries to somehow take his info into Domain A (which is no longer active) instead of the current one Domain B.

Now if, he clicks login WITHOUT using the fingerprint reader, it shows the correct Domain B login. We looked through the registery  and found an entry for the lastdomainlogin or something like that that showed Domain A, we changed it, to Domain B, rebooted, tried the Fingerprint, it still showed Domain A once again. We believe there is something hard-coded somewhere in the applications Dell Embassy Suite or something that is causing this issue now.

Any thoughts or suggestions or ever come across anything like that?

The settings for the biometric can be hard coded (written somewhere deep) into the software once it is setup. I would either remove the biometric profile completely or remove the program with something like revo uninstaller and reinstalling to try to remove any fragments of the old biometric profile.
