unable to ping using netbios name

[Jeff]

Hey

I've got 2 computers in my home network, these computers are connected to
each other via a router

pc1 has winXP pro + sp2
pc2 has win2k3

Each computer can ping the other using it's IP address... but not by using
netbios name.
When I ping using netbios names I get this message:
"Ping request could not find host PC4. Please check the name and try again."

WINS is installed on the win2k3 computer

The winXP computer are using dynamic IP (DHCP), while the win2k3 computer
are using static IP address. The winXP computer has had the same IP address
for years so I don't see any difference here between static and DHCP.....
well, I'm a newbie on this so I can easly be wrong! Both computers are on
the same subnet

I've created an active directory on the win2k3 computer. an AD containing
only the domain controller... I want my winXP machine to be
member of this AD, but first I think these 2 computers must be able to ping
each other using netbios names. As the win2k3 machine has AD it also have a
configured DNS

in WINS tab in "Advaced TCP/IP settings" on the winXP machine, should I
enter IP address of the win2k3 computer?

any suggestions?

Check to see that the service "Windows firewall/Internet connection sharing" is
started, that was an issue I had at a time gone by.

I've fixed it so the computers can ping each other. But for this to work I
had to turn off firewalls on both computers.

But having firewall turned off is not an ideal thing. So here is the
problem: what exception shall I allow on the firewalls so the computers can
ping each other using netbios names ?

Please do not snip the posts so others can see what has been suggested and tried.

That's not fixed by any means, if you weren't behind a router you'ld be courting
disaster.

Did you even try what I suggested? What secret firewalls are you using?

Thanks, both computers are running the "Windows firewall/Internet connection
sharing" service

Both computers are using the windows firewall.... that firewall which is
installed when installing win2k3 and came with sp2 of winXP

These 2 computers are connected to each other using a router/gateway. These
2 computers share the same internet connection. Internet cable from the ISP
is connected to the Ethernet cable/DSL port on the router. I got internet
via the cable. This router is an standard 3com router with hardware
firewall... but in addition I would like both computers to have the windows
firewall enabled.. Any suggestions?

I'm not sure why they can't be pinged by UNC. I have 2 routers, one each for a
different subnet and both subnets have machines getting their IP via DHCP and
statically set IP's. The only times I run into problems being able to ping by UNC is
when the service Windows firewall/Internet connection sharing" is not running.

Maybe you can find something in any of these that may spark a clue:
