I brought a laptop home from work that logged into a domain. Since I do not use a domain at home, I went into the computer identification tab and clicked the option to workgroup indtead of Domain. The OS requested that I restart the computer, which I did. When the computer comes back up, it asks for my password, but will not accept the password that I was using while it was part of the domain. In other words, I cannot get past the logon screen. I do not know the admin password at this time. Is there anyway to get the login to use the old domain username/password combination. Or is there some other way to get things working again.

This question has been asked and answered many times on this site alone. Assuming this is a work computer, why would you remove the Domain login option? You still would have been able to login with your regular userid and password, since by default those are cached. If you don't know the Local Admin account user id and password, (or if you don't have a local account) then you won't be able to login. Take it back to work (with your tail between your legs) and have your IT people fix it. Life's more painless for the brainless.
