Alright, I should have been a bit clearer...
I have no firewall software active - I have it installed, but found no use for it because my VirusScanner scans every file instantly upon modification/creation.
So, I have no firewall enabled, and it looks like I need port 4662 and 4661 to get on the server.
My question: how do I check these ports to see what is using them or unblock them??
