"ping -a" does not resolve hostnames in XP Pro

[G Rakaska]

I searched for this topic in this group and the "general" group. I
found a few articles on this subject, but they had very few responses.
The responses only stated "check your DNS settings" or something
similar.

We just installed several new XP machines on our network (the first XP
systems on our net). We use DHCP to set all related settings, we have
an NT4 domain.

Other O/S (win9x, NT4, w2k) resolve hostnames when executing "ping
-a", but none of the XP machines resolve. The XP machines can ping any
host by name or IP, and can be pingged by name or address.

ipconfig /all reports the same information on all O/S, including XP. I
searched the MS kb for this and found nothing. Hopefully someone here
can help.

Thanks!

I'd bet you have a firewall somewhere blocking name resolution
(similar to file sharing). Start with the XP machines, then check the
others. Disable ICF, un install any third party firewall if you can.

If that ends up being the problem, then re install firewalls, and set
them to trust the other computers. Allow the following traffic
between trusted computers: "TCP 139, 445; UDP 137, 138, 445".

Paranoia comes from experience - and is not necessarily a bad thing.

Thanks for the reply. I just checked the ICF and it is not running,
there are no other firewall programs running. All PCs involved are on
the same side of the PIX firewall.

Additional information:

I executed ping -a using the PC's own IP, and it resolved its
hostname. (not much help, I'm sure, but at least it know its own
name!)

I ran Network Diagnostics (Help and Support Center) and all functions
"passed".
