Win98 - exceptions.IOError: (13, 'Permission denied')

[Robert Dollinger]

Hi to everyone,

I have a Service, that runs on a WinXP machine. The service read a file 
on a Win98 machine and write the content in a file on the WinXP machine.
After tree times I get the error message exceptions.IOError: (13, 
'Permission denied').

The following things I have already tested:

- The file on Win98 machine could be deleted, so the file is closed 
correctly.
- Stop an restart the service on WinXP, will have no effect
- Reboot the Win98 machine solve the problem for three times. So I have 
the same issue explained above.
- I have changed the intervall from 5 sec to 1 minute. After ther first 
time I get the error message.
- Using a Win2000 or WINXP machine instead of the Win98 machine. That 
works. But unfortunatly the PC to access is a Win98 and I have no 
influence to decide for upgrade.

I can't figure out, what's the problem.

This is the code to simulate my actual problem:

     _svc_name_ = "TCTest"
     _svc_display_name_ = "TCTest"

     def __init__(self, args):
         win32serviceutil.ServiceFramework.__init__(self, args)
         self.stop_event = win32event.CreateEvent(None, 0, 0, None)
         self.overlapped = pywintypes.OVERLAPPED()
         self.overlapped.hEvent = win32event.CreateEvent(None,0,0,None)
         self.thread_handles = []

     def SvcDoRun(self):
         import servicemanager

         servicemanager.LogMsg(
                 servicemanager.EVENTLOG_INFORMATION_TYPE,
                 servicemanager.PYS_SERVICE_STARTED,
                 (self._svc_name_, '')
                 )

         while 1:
             datei = open(r'\\ipcwin98\test\test.txt', 'r')
             log = open(r'c:\log.txt', 'a')
             log.write(datei.read())
             datei.close()
             log.close()

             if win32event.WaitForSingleObject(self.stop_event, 5000) == 
win32event.WAIT_OBJECT_0:
                 break

         servicemanager.LogMsg(
         servicemanager.EVENTLOG_INFORMATION_TYPE,
         servicemanager.PYS_SERVICE_STOPPED,
         (self._svc_name_, '')
         )

     def SvcStop(self):
         self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
         win32event.SetEvent(self.stop_event)

if __name__ == '__main__':
     win32serviceutil.HandleCommandLine(MyService)


Thanks in advanced for your help.
