Hi David,
Thanks a lot.
As I have pywin32 already installed this is probbaly the way to go.
Meanwhile I implemented already a small module, which is parsing
sc.exe's output, but probably 'll change it as my implementation is a
little clumsy.

Dear Folks,
In previous versions of Python I used to use e.message() to print out
the error message of an exception like so:

print e.message()
Unfortunately in Python 2.6 the message method is deprecated.
Is there any replaceme
