Ok, here's an odd one... Not sure if its a M0n0wall problem or not (home 
network: Cablemodem-> m0n0wall_1.22-> several_computers_on_lan)

One Windows XP machine often won't connect to shares on other machines 
that are on the LAN.(connect network drive \\hostname\sharename) BUT if 
I *ping* the IP of that machine (the PC with the share I'm trying to 
connect to), and THEN connect to the share using the hostname, it works 
every time!

So, I can always connect to the shares using the IP, and I can connect 
using the netbios name IF I ping the server first. Anyone heard of this 
before?
