Thanks, Steve, for the quick response. I assumed it was at the server side as well, but after being frustrated with the problem on the network cut of my control, I disconnected and scanned the ports on the network behind my own router and encountered the same lack of open ports. Then I performed the same scan from another machine that resides in my network, and found several open ports within seconds. I’ll look again, but as far as I know, the problematic computer has the firewall turned off.
Nevertheless, thanks for the input.
Regards,
Steve
