How should I configure Windows Firewall to allow communication between various components?
When you have the RXServer running on Windows 2003 Server and the Spooler Client on Windows XP, and the Windows XP computer has the Windows Firewall turned on, you need to have “File and Print Sharing” turned on in order for the communication to work. Otherwise the XP firewall will block all incoming messages from the RXServer to the Spooler Client resulting in jobs paused all the time since RXServer cannot send release messages to the SpoolerClient. See figure below.
