Question : how to determine port numbers on SBS 2008 firewall

I need to see if certain ports are opened on the SBS 2008 firewall. The problem is, I can only see a description of the port, but not it's number. How do I see the actual port numbers?

Answer : how to determine port numbers on SBS 2008 firewall

I think the best way is to port scan the server from another machine.

NMAP is the most comprehensive port scanner http://nmap.org/ as it will give you info about the listening services

Blues port scanner is very fast and simple www.bluebitter.de/portscn2.htm

Make sure you turn of any AV/Filtering/Firewall on the computer you are scanning from
