NSClient

Depending on how many connections you have to your exchange Server, you
should choose a pretty high Port number, to prevent this problem. For
every Client Connection to the Exchange Server, Exchange just takes a
new Port, starting with port 1024 (i guess).
You got 2 other solutions to solve this Problem:
1. Configure Exchange to start a Port Number 2000 or so to grab Ports
2. Let the NSClient start BEFORE Exchange starts. Exchange won't grab
the Port when it's in use.
