I have to apps that communicate using remoting. This works fine on a

When I run the same on a terminal server I get an error when

Why do I get this error? How can I resolve this Issue

The problem you have is due to the fact that you cannot open more than
1 port on the same computer.

I had the same situation lately. The solution I used is quite
simple. I get the session id from the terminal server and add it to
my port. That assure me I got a unique port for every session. To get
the remoting session id use the following method:

[System.Runtime.InteropServices.DllImport("kernel32.dll")]
static extern bool ProcessIdToSessionId(uint dwProcessId, out
uint pSessionId);

public long GetRemotingPort()
{
uint sessionId = 0;
System.Diagnostics.Process currentProcess =
System.Diagnostics.Process.GetCurrentProcess();
bool result = ProcessIdToSessionId((uint)currentProcess.Id,
out sessionId);
return 65000 + sessionId;
}

In this example, I removed all error trapping validation. The base
port i was using is 65000 and if not on a terminal server, the
ProcessIdToSessionId returns 0.

Nicolas,
thanks for your good solution. Can the port number ever be to big?
What's the max for the session id?
