how windows service finds another .Net component

[BBM]

I am new to .Net.
I have a Windows service in C#. It is going to use another .Net component
(DLL) made by a 3rd party company. If I start my program as an app with that
DLL in the same directory, my program can use it. But if I start it as a
service, it does not work. How does a .Net windows service finds other DLL?
From "path"?

I suspect your problem isn't the app finding the DLL, but rather that
applications can't be started as services (at least not without a bit of
tricky code). What is the exact error message that you are receiving?

The service can be started and running.
I can write out a text file in my code.

The 3rd party .Net component I refer to indeed is Apache log4Net.
No log file is created from it, so I don't know whether the service can find
the log4net.dll. Should the log4net.dll be copied into C:\windows\system32 ?
My own text file is found in C:\windows\system32 so the "current" directory
must be "C:\windows\system32".

Does a .Net windows service require a manifest file?

You usually have to place the called DLL into the GAC, which means that it
must be strongly named.
