Your prompt help is greatly appreciated.

I have my work laptop at home. I have done something that now prevents
me from rebooting and loggin in with username/password.

The alert at startup tells me that either my user/pass is wrong or the
domain is wrong. The user/pass is correct, so I must have altered the
domain.

Now I cannot login. I have tried rebooting with F8 pressed down and
restarting with the last working configuration...no luck.

What do you suggest? I really appreciate any help.
