hi Arno
I am running ICS in a nt service and i am using multi threading but the
socketservers is in the main thread. The threads only do some work with a
database and validation of the information received from the machines and in
the end the threads make a send call.

Miguel, are you running ICS in a multi-threaded application
or in a NT-Service?
