[python-win32] Service fails on mapped network drive

[Martijn Ras]

Heya Folks,

Since i updated my script so it can be run as service, it fails to work 
on files that are located on mapped network drives.

1) Share the root of your drive C.
2) Map the network drive.
3) Create the following three files in the root of your drive C
    Note: Replace the following in the python script files:
    <LOCALHOST> with the name of your machine,
    <SHARE> with the share name you specified in step 1),
    <MAPPEDDRIVE> with the drive you specified in step2).
4) Run 'python execfile_test.py', it will print "dit is een test" three
    times, as expected.
5) Install the service 'python execfile_test_server.py install'.
6) Open the services control panel:
    a) change the logon so the service run under an account that has
       sufficient rights on the mapped network drive.
    b) start the service.
7) Open the EventViewer, select the Application log.
    You'll notice "dit is een test" has been logged twice and the third
    loggin an IOError 'No such file or directory'.

Any suggestions on getting this service functioning one mapped network 
files?

Mazzel,

Martijn.
