"Lost" PCs on local network.

I made a small (?) change to my network this weekend to connect my Tivo.
Because I found myself having to frequently reconfigure a LinkSys WAP and
Client set-up before I could get it right, I finally gave up on trying to
force the LinkSys to use a 192.168.0.n address and instead allowed it to
default to 192.168.1.n and changed my D-Link router from the .0 setup it
wants to use.

Some time later when Tivo and everything was working we noticed that none of
the PCs could "see" each in the Windows network any more.

All PCs can ping each other no problem.  I can connect to both the LinkSys
AP (.245) and the Client (.246) for configuration purposes.  I have also
checked to see if other PCs can connect (using the IP address) to the Apache
server running on my laptop.  This works just fine.

All PCs can see the internet no problem.

PCs are running a mix of Win 2K and XP.

I have rebooted the PCs with no effect.  I also enabled NetBios over TCP/IP
on two of them which was the suggested fix from one web page I found.

I'm clueless - anyone got any suggestions?
