Hello!
I have made a simple queued component with C# .NET (source code below). But
when I try to run it I get an error message in the eventlog (see below).

The messages end up in the dead queue in MSMQ. The target computer is a
Windows 2003 Server. When I run the same program on my Windows XP-machine
everything works just fine.

I register my program with regsvcs and start it with Right-Click-Start in
COM+. The user account that runs the COM+-program has full rights to the
public MSMQ-queue and the private ones.

I'm running out of time and ideas. Any help would be very appreciated.

Best regards
Niclas Forsell
