Loose User under

I am running windows 2000 professional on a pc that is networked – The server is using windows 2000 server. I had to reboot the pc when it came back up it signed on as another user and I lost all the programs and the ablility to print. I could locate the programs, but am having problems with the printers the system will not let me install a default printer. I tried uninstalling all the printers and then re-installing them, but no luck. Any idea on how to get the original user back on this pc or a least the printers? The pc original signed on as ted to network now I have ted, ted000, ted001, and ted002. It seems that the pc is running from ted002.
