I try to create a Windows Service which listens to UDP port 514, i install it using installutil.exe and i get the following error message:

---------------------------
Services
---------------------------
The SyslogService2005 service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs.
---------------------------
OK
---------------------------

In practise it starts working till the progressbar in Properties Window ends!

my code:

                // Do some work while we wait for a message. For this example,

Does it work if you tell it it can interact with desktop, or if you run it as you rather than a local service account?

i created a console application with the same functionality and it is working properly!
What the **** with the windows service! The service manager cannot understand that it started ... :(

Depending on which OS and wether you're part of a domain etc, windows 2003 for example is common to have it so you cannot interact with the desktop.. if it thinks for any reaosn you might, the service doesnt work.

What type of interaction? (Development is on Windows Vista)
In most tutorials in OnStart section they create just a event in EventLog or they write service started in a txt file ("Service Started") and they create another event in OnStop section... I just have more functionality in my case...
