           Summary: NetTcpBinding Callback generates error when one client
                    triggers a call back for another client via WCF Server

Source Code  to reproduce the bug

User-Agent:       Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_1)
AppleWebKit/535.1 (KHTML, like Gecko) Chrome/13.0.782.220 Safari/535.1

I have a WCF Server that registers clients callback and call it when "Dowork"
method called.
If I have only one client registered the call back works OK. But if I have two
clients registered the callback get's executed for both clients but the the
last callback generates this error on the WCF Server side:

Reproducible: Always

Steps to Reproduce:
1. Have one NetTcpBinding WCF Server with Callback
2. Connect two clients that register their Callbacks
3. Trigger callback so that the server sends call back to each client
4. Get the error message on the server side
Actual Results:  
The client hangs and later time-out

Expected Results:  
All callbacks executed and the WCF server is ready to accept more calls.
