Great. I could make my service working with this snippet:

import sys
sys.path.insert(0,r'C:\Python24\DLLs')

But this is very ugly. Primarily, I do not want to use absolute path 
names in a this program. I want to use the same code on different 
computers and operating systems, but this code is not portable. 
Secondly, I do not understand why sys.path is different when I start 
python interactively. I believe that sys.path should be the same when 
starting the program as a service. The only difference between the 
application and the service is that the 'main' program of the service 
imports some additional modules. See them below.

iT:\Python\Projects\NamedConnector>python
Python 2.4.1 (#65, Mar 30 2005, 09:13:57) [MSC v.1310 32 bit (Intel)] on 
win32
Type "help", "copyright", "credits" or "license" for more information.
 >>> import sys
 >>>
 >>> s1 = str(sys.path)
 >>>
 >>> import win32serviceutil, win32service
 >>> import pywintypes, win32con, winerror
 >>> from win32event import *
 >>> from win32file import *
 >>> from win32pipe import *
 >>> from win32api import *
 >>> from ntsecuritycon import *
 >>>
 >>>
 >>> s2 = str(sys.path)
 >>>
 >>> print s1 == s2
True

I cannot distribute my service until I make it independent of the python 
installation directory.

Why sys.path is different when starting the code as a windows service?
How can I make this code portable?

By the way, you have been a great help. Thank you very much. I can now 
continue working.  :-)
