Is there a host-based firewall in use (meaning on the localhost)?

Can you test out this for connection on the same subnet (that would not traverse a router) vs. connections from clients not on the same subnet?

This sure smells like a network issue where (translated) connections are being timed out.

Start working with the network techs to see if they have any ideas.
