New “user” in Documents and Settings

One of secretary’s computers has suddenly created a new “user” in the Documents and Settings folder. Usually there are 4 – Admin , All Users, Default User, and Jane Doe (the secretary). Yesterday morning, a 5th new “user” had appeared as Jane Doe.JANE
This new user apparently seems to be the default now when Windows (2000 Pro) starts. It acts as if no one has ever logged into windows (welcome to word, excel – outlook express was empty). I was able to import most of the information I needed to Outlook, Excel, and some other programs, but it still isnt quite right. Has anyone seen this before? If so, how would I get Windows to to read the Jane Doe user and not the Jane Doe.JANE?
