I changed my domain name, now XP will not accept my password and I am locked out of Windows. Any suggestions?

Do you have an account on the new domain ?
Are you entering the correct information for this new domain ?
Does this computer have an account on the new domain ?

Are you on a network? Did you talk to your IT people?

Can you login to your local account? If so you can change it there if not there is a password recovery for lost administrators password scattered all over the net. You just have to pic one. Download it and install. When your done recover the password and charrrang you can change the domain name back to its original state.. :) but be sure to ask permission first on the IT Dept. :)
