1.  Are you behind a "wireless" home router?

2.  IP Address.
     a.  Can you ping the "unknown PC" to get its numeric IP address?
     b.  And the IP address of this "unknown PC" is not your default gateway (home router)?
     c.  Any other network nodes connected (print server, printer)?

3.  What operating system(s) and service pack levels are you using?

4.  You might want to chew on these links:

Thanks for the help I ended up fixing the problem by redoing the security on the router an redoing the network over. I guess I was just being lazy an that's what I should of done from the start. Thanks again...
