Re: "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?

Just one suggestion ...
- if you are using DHCP, manually set an IP of one of them outside of
the DHCP range and see if you are having the same issue.

And some questions ...
-- can they ping each other by name, or only by IP address?
-- is the same device giving out addresses?  Perhaps are BOTH devices
running DHCP and getting confused?
-- Is the problem universal, or restricted to devices trying to talk
across the wireless AP to the wired switch?
-- Do the W2000 and XP systems behave differently?
-- when you futz'ed with the configs on the devices, did you see any
settings related to NETBIOS, DNS, or file sharing  that perhaps you
changed trying to make the old address scheme work?

Name resolution in Windows  is kind of weird.  If you let is all run a
few days it sometimes straightens itself out as caches expire, etc.

Good luck!
