Change Communication ports

I am running Acronis Backup and Recovery 10. I am having problems using the remote management console to do installs and to manage all of the workstations. It seems to be a port issue to me as far as I can tell. I used telnet to check the ports and I can communicate to the server from the workstation fine on all ports. When I telnet from the server to the workstation I cannot get a connection. I tried various ports (80, 443, 445, 25001, 9876, etc). My workstation is Windows XP SP3. I have tried enabling and disabling simple file sharing without any results. I have disabled the firewall on both the server and the workstation. I checked the AV and do not see any port blocking enabled. This environment does not use DHCP - all names are resolved via the HOSTS file. I did all of my testing using the IP address instead of the name. I have local admin rights on the PC and on the server. I can do a local install of the client on the PC and do a backup and recovery without issue, but the central management piece is not working - even after the local install.

Assuming that the port being blocked is the issue, what do I do? How can I see what is blocking it? I created an explicet "allow" rule in the local firewalls on the server and worstation for various ports to no avail.
