I have FW-1 4.1 sp2 running on Nokia 440. WINS does not seem to be
communicating thru our firewall  to a trusted network. TechNet says to make
sure that ports 42 & 53 are open on the firewall. Is there a way 1.)to tell
which ports are already open  2.) to run specific services thru specific
ports 3.) to find out what ports predefined & installed services are using? 


I was also wondering if there is a resource available to help me understand
what each service does?

Thanks for all your help.

Dave J.
