Spent about 2 hours pouring over IIS, Server 2008, networking, my code and my networking buddy decided to change the Connection Timeout time in my IIS website to 8 mins instead of the default 2 mins. -- It fixed
the silently thrown RPC error i was getting on both XP and 2k3 and let the data send. We're not sure if this is the
fix or just a work-around for now.
I'll keep this thread updated as I find out more for anyone else out there on the net.
