[BC] Networking question:

[Glen Kippel]

OK, Brainy People -- I have a problem.  One of our audio recording/editing
computers went up in smoke and I moved the hard drive and sound card over to
another computer.  Everything looked good on the workbench; I could connect
to the internet, etc.  But when I put it back in the control room it won't
connect to the network.  No servers, no internet, nothing.  All I get is
"Limited or no connectability."   The router shows a light when it is
plugged in, and it goes out when I unplug the cable.  Running Network Setup
Wizard doesn't get me anywhere.  It's like it's giving me the wrong IP
address.  What am I doing wrong here?  Any input would be appreciated.
Thank you.
