I've never seen this as described, but it sounds familiar - most services I work with tend to be either LocalSystem or with their own "dedicated" account, which both avoid this issue. When you log out, applications running under that account may be sent a "control handler" with CTRL_LOGOFF_EVENT event and may have certain system calls interrupted. You may like to look into win32api.SetConsoleCtrlHandler() and see if explicitly handling/ignoring that event helps (looking at the MSDN docs for this function will also be vital) Cheers, Mark

The service is installed correctly and set up to run automatically on startup, which it does. The machine boots to the logon screen and the service can be verified to be running correctly. If I now log onto the machine as administrator, the service is still running. When I log off however, I return to the windows logon screen, but the service seems to have stopped. Logging back in as administrator, the Windows services screen says the service has stopped. When I check the system log for applications, the following is logged: The instance's SvcRun() method failed File "C:\python24\lib\site-packages\win32\lib\win32serviceutil.py" line 742, in self.SvcDoRun() File "C:\myservice\myservice.py" line 123 in SvcDoRun time.sleep(5) exceptions.IOError: (4, "Interrupted function call") What does this mean? Why does logging out of the Admin account affect a background service? Is this a known issue? I've copied the example and modified very little. My service is effectively an infinite loop that periodically checks if the 'real' server process (another python program) has died, and if so restarts it. Is this some weird issue with using sleep within the service's main method? If so, how can I get round this problem? I'm using pywin 2.0.4 and python 2.4.3 Thanks for any help anyone can give :-) Tom
