Assuming the service is your project, build it in debug mode. Open the
project. Set any breakpoints that you want to set. Use the SCM to start
the service. Use Tools->Attach to process.

Debugging services are an absolute pain in the ass. Literally. Mostly you
cannot begin debugging them until all the really interesting stuff has
completed, since your mainly dependent upon being able to attach to the
service and you can't do that until it is attached. The VS documentation
will get you there, and check newsgroup archives here and on the NtDev list.
I asked the same question about a year ago and received some good
information. However, I haven't used it for about a year so it's stale and I
don't remember all the gooey details. Search the archives for my name and
you should get some hits.

Sure you can debug service startup! Use gflags.exe to set up
the debugger for your service - it'll start as soon as the service
is started. (I know this is theory, but I haven't actually debugged
a service in this way myself...) You need to have Debugging
Tools for Windows installed on your machine:

FWIW, you can modify the registry manually the same as gflags does, so you
don't need to install the Debugging Tools.

If your service starts during system startup then, yes, that can be
challenging to debug. The best way to do that is to attach a kernel debugger
to your system, and put a breakpoint in your service startup code.

there is 2 possible problems:
1. check start up code (initialize service)
about this case - it's quite common task and should not be difficult
2. check internal logic of service
I guess with (2) no problem -you just debug service as usual executable
process (with small modifications in start up part)
