unavailable network names!

3 machines in a workgroup named WORKGROUP.
c3po= win98
r2d2= win2000 pro, no firewall, no AV, fresh install, LNE100TX card with
latest drivers.
HP= win2000 pro, no firewall, no AV, fresh install, LNE100TX card with the
latest drivers.

c3po and r2d2 can copy files from each other just fine.
c3po and r2d2 can copy files from HP just fine.

However, when HP tries to copy files from c3po or r2d2, the hub's lights
flash normally at first, then flash slower, then stop.

Then I get "The specified network name is no longer available." on HP. Then
HP times out when trying to ping the gateway, but restarting HP fixes it's
network connection again.

At first I was testing with no service packs on either of the 2000
computers, then with SP3 on both of them. Same results as above.

I can find nothing on MS KB or technet about this error. I assume it has
something to do with the browser service, but I can't find much info on
messing with the browser service on win2000 machines.

Thanks for any help,
-Sean Benjamin
 
I doubt it has anything to do with the browse service, sounds more
like an intermittent connection problem. Look in Event Viewer for any clues.
The next time it happens run netdiag [on install cdrom support/tools - run
setup] on it to see what it reports. I would try a different cat5 cable from
that computer to the hub, and on a different port if one is available. It
would be a good idea to reseat nic and try a different pci slot - avoid slot
next to agp card. Review the properties on the nic and compare it to the
other functioning computer with the same card. The nic itself could be
suspect - try a different one if you have one handy and nothing else seems
to help. See KB articles for more info. Good luck. -- Steve

These are brand new network cards in both 2000 machines, new cat5, new hub.
No change in results.

Event viewer reports nothing wrong on either HP or r2d2. I went into the
registry (Q136712) on r2d2 and set IsDomainMaster to 1, and
MaintainServerList to YES. No change in results.

I even tried setting LMannounce on both HP and r2d2 to 1. No change in
results.

HP still will not copy files from other computers, getting "The specified
network name is no longer available." still.

I'm thinking about buying a new motherboard for HP at this point....

Interesting. If the HP has an onboard nic, make sure it is disabled.
If netdiag did not show any errors, the only other thing I can think of is
check the security options on the W2K computers. Possibly if there are
mismatched settings for smb signing [the four digitally sign communications
settings], there could be problems - though that would be unusual since I
believe you said they were new installations. It might be worthwhile to
disable those settings on both computers. The other thing worth trying would
be to use a packet sniffer on the computers to try to see what is going on -
there are free ones for download. Run netstat -e at the command line on the
HP computer next time the problem occurrs to see if there are a lot of
errors. I would first try another nic of a different brand [they can be bad
out of the box], or a reinstall before resorting to a new motherboard. ---
