So, the first problem was that the main computer was sitting behind a firewall that has SPI (stateful packet inspection). Unauthorized application socket connections not explicitely defined are dropped.
Secondly, the client and server are on different network subnets joined by a router and as everyone knows routers do not forward broadcast packets which WideFS uses for discovery (Duh!). Defining a static route directly to the server solved to problem. Most won't encounter this problem...but if you do
Okay, the easy technical stuff aside, I am stupified that I didn't realize the true power of WideFS, ergo Distributed Computing. MSFS CPU dedicated to MSFS and as many CPUs dedicated to other applications as you want!!!
I was experiencing stutters with AS6 when it updated the weather on the fly and RC v4 when it compiled wav files to play ATC commands. FDC drops frame rates also. At the end of the day, with an AMD FX machine, I would end up with a stuttering and frustrating mess. BUT with WideFS it would appear those days are over since I am now distributing Applications over 2 seperated comptuers leaving my FS machine free to crunch scenery, traffic and graphics.
Wow, I know I'm late lauding the praises of WideFS but this darned thing actually works! Changed my FS experience in spades!
