I used Windows NT 3 to 4 and that's how you would log on back then. The CS\Cporter would be the domain name or possibly the local login. It's your machine so I expect you to recognize the machine's name and accounts.

http://support.microsoft.com/kb/308226 documents how to change the login.

I can't tell why it changed but the effect is well known and documented.
