Hi Mike sorry for just replying now but I was away.
1st thing is that server app is what is the method signature the server hap has for receiving messages? cause based on your example you where sending an array of bytes to the server app not a string, is the server app done in .NET or are you using com interop to connect to them?
Are you connecting from the client directly to the server app or does your client connect to a proxy that connects to the server app?
