Cannot ping.... problem

[Jeff]

Hey

I have 2 computers set together with a router between them.

One of the computers is using XP Pro sp2 (firewall enabled) as operating
system. the other computer is using Windows Server 2003 as operating system.

From the machine with W2k3 I can ping the XP machine using the ip address of
the XP machine. I cannot ping it using the name of the XP computer...

From the XP computer I cannot ping the w2k3 machine using either name or ip
addresss..

In the firewall settings on the XP machine I've enabled all the ICMP
settings in Advanced tab...

Both computers can ping the router.

The w2k3 installation is fresh, just a few hours old. It's an 180-days
evaluation version of the Windows Server 2003 Enterprise.

Any suggestions?

Jeff

Okay, now from the winXP pc I can ping win2k3 pc using ip address.

But I cannot ping using their names. What am I missing here?
