win32 Service: path to .py script

[Gregor Horvath]

Hi,

I have a testservice.py (see below). I installed the Windows-Service
successfully. (via commandlineopti on install)
The problem is that it runs only when it is in c:\windows\syst em32 or in
the python path.
I added the desired path (Y:\) to the PYTHONPATH environment variable
for the system account and rebooted.
When I start command line python and do a import testservice everything
is fine.
Starting the service with the script only in Y:\ gives the error in the
event log:

Python could not import the service's module

exceptions.Impo rtError: No module named testservice

Thanks for your help.

I believe that your problem is that services run under Local
System account. Normally Local System account would not have
a drive mapping Y:\. You can change the account that a service
runs under in the Service Manager-Log On tab. Normally you
wouldn't run services from mapped drives, they would be
installed on local machine and started from there. If services
need to access mapped drives, you need to put full UNC
pathnames to access them or run the services under an account
that has the drives mapped properly.

You are absolutly correct.
I moved the script to a local drive instead of a mapped network drive,
now it works perfectly.

Thank you a lot.
