Help-Home Network Disappeared

Hello. I got a new laptop and added it to my home network and everything was
fine. I brought my laptop to work today and my coworker went online on our
wifi network there. He did say something about adding my computer to the
work network, but said it wouldn't affect my home network.Tonight when I got
home I found that my home network had disappeared. The only computer shown
when I click on to view computers in my workgroup is my new computer. My
desktop is gone. When I first go to My Network Places I see icons for
shared folders on other computers on my work network. When I check to see
what printers I have, I see my network printer and a work printer listed (I
never installed this printer), but I cannot print with my network printer
because my printer is gone. Any idea what happened? And how do I fix it?
Thanks.

It sounds like he put it into the domain at work and you are now logged
in to the work domain using cached credentials.

Log out.

Log in again but make sure the domain entry in the logon window is
the name of your computer and not the domain at work.
