Thanks for responding.  I'm just trying to do exactly what I was able
to do before...open Network places and see the computers identified by
their machine name. No changes otherwise.


What's the topology?  A hardware firewall shouldn't be doing anything to
local network connections, and their name resolution should not depend on
the Internet.

I'd be thinking along the lines of local security settings, perhaps due to a
W2k update?

Topology is 501 connected to cable modem and 4 computers connected to
the 501's builtin switch. Two way communications OK between computers
and internet and can ping by computer name - names just don't display
in NETWORK PLACES.

The "problem" began immediately after the changeover...no changes of
any kind was made to the networked computers other than changing them
from static to dhcp...thats why I think it has something the do with
the firewall or more appropriately it's configuration. I'm beginning to
wonder if the builtin 4 port switch works differently than the earlier
plain vanilla switch - is it possible that the firewall is interacting
in some way with the builtin  switch such that I need to configure
"something" for NETWORK PLACES to work?

thanks



It really shouldn't be, you could verify that by sticking an extra switch between the workstations and the firewall. Have a look at the routing tables, I guess it's possible the router handed down a route for broadcasts? Though I've never seen that done. Hopefully someone who is familiar with the 501 will chime in.

By way of a diagnostic, I think I'd change 2 machines back to static IP's, the same ones that they were previously assigned dynamically, see if those two can browse each other. If so, compare their routing tables to the dynamic machines and see if there is anything different.

-Russ.


the switch & router are not to blame, it's the DHCP vs static assignment. go back static or map your MAC hardware addresses to specific ip-addresses. Once ether of these, add your LMHOSTS and you will not require a local DNS service.

you've got it right when you can PING other-system-name.

now your active systems will display in
networkplaces->ms-win-net->Workgroup as individual host names
