Windows 7: Cant get into Windows7

LoL I feel so stupid right now. I work for my local government as their IT person. We just purchased 8 dells to replace older workstations. I am setting up the accounts on the new computers and adding the computers on our domain. Here is where I fracked up. Windows walks me through creating an account on the local machine. Easy enough. Then I go and add the local machine to the domain. There active directory has all the usernames and passwords stored and logging on the domain is good. THen I go back to User accounts and delete the original account that windows helped me setup just to free up space. Well dummy me also took the computer off our domain and back to the default workgroup and then restarted the machine for it to take effect. So now I am back to the login screen and I cannot login with any name! I need help lol. I can't find a solution for this at all!!!!!!!!

Sounds like quite a fix huh?

Try this....boot the computer with the Windows 7 DVD->Click "Repair Your Computer"->Choose the second radio box and click continue->Choose the command prompt option (last option)->Try the following commands....

EX. net user SFT password /add

EX. net localgroup administrators SFT /add

If that doesn't work we will try something else!
