FSBUS network

hi to you alli hope you can help me with my FSBUS network, i cant get it to work as it should,here is a step by step guide to what I did and please correct me where I am going wrong.1. This is where I started --Start--control panel--maintenance--system--hardware--devices and continued on to the ports from there to the FSBUS port which is "USB serial communication"on PC2.I continued to change the port settings to COM4 and exited then I went on to PC3 and changed the FSBUS to COM4.Both COMS are connected then I started a test to see if it was working.In PC2 I have the overhead configuration and the FSBUS is working ok and in PC3 is the radios and TQ and FMC that wont work or cant be seen . The FSBUS USB connection, I had in PC2 and changed it to PC3 and it seems that whatever PC has FSBUS USB connection will work but the other computers that are NOT connected directly into the FSBUS connection will not work over the network.2. Here is the software for each of the computers on the network which is all connected to a LAN HUB.All seems to be working okay judging by the Project Magenta software as this is working very wellover the 3 computers and windows xp pro and service pack 1.Computer 1 -- FS2004--FSUIPC--PM IP 169.254.212.101Computer 2 -- PM--WIDEFS--FSBUS IP 169.254.255.92Computer 3 -- PM--WIDEFS--FSBUS IP 169.254.141.167I changed the IP on the FSBUS broadcast to the FS PC and no luck ..e.g 169.254.255.255 to be seen over the network .3. All versions of software for the flight simulator are right up to date except for FSBUS which 2.2.1.the cockpit systems i got from symulatory and or full working ..just no over my network i have FSclient running on PC3,, do i need to configure the FSclient.ini or edit in any way any help or links to help me would be greatfull please please help kevin
