From: Maria.Reinhammar on 20 Sep 2006 08:42 I have an app using active_directory.py and the std module asyncore in a Windows Service. Works perfectly! That is, until I try to use py2exe to create a standalone (need to avoid installing the entire Python etc. on the target system). When I try to start the installed Service, the system tells me it terminates prematurely and in the event log I find: The instance's SvcRun() method failed File "win32serviceutil.pyc", line 785, in SvcRun File "XXProxySvc.pyc", line 126, in SvcDoRun File "XXProxySvc.pyc", line 94, in setup File "D:\projects\XXProxy\DB.py", line 54, in loadFromAD File "active_directory.pyc", line 402, in search File "active_directory.pyc", line 398, in root File "active_directory.pyc", line 371, in AD File "active_directory.pyc", line 378, in _root File "win32com\client\__init__.pyc", line 73, in GetObject File "win32com\client\__init__.pyc", line 88, in Moniker pywintypes.com_error: (-2147221020, 'Invalid syntax', None, None) The offending line is: import active_directory as AD .... for item in AD.search ("objectCategory='Person'"): .... I.e. the call to AD.search() is the entry point to the problem. The setup.py is (pretty straight forward..): from distutils.core import setup import py2exe class Target: def __init__(self, **kw): self.__dict__.update(kw) # for the versioninfo resources self.version = "0.9.0" self.company_name = "My Company" self.copyright = "My Company (c)" self.name = "FilterProxy" ################################################################ # a NT service, modules is required myservice = Target( # used for the versioninfo resource description = "AD Driven Mail Filter", # what to build. For a service, the module name (not the # filename) must be specified! modules = ["ProxySvc"] ) excludes = [] setup(options = {"py2exe": {# create a compressed zip archive #"compressed": 1, #"optimize": 2, "excludes": excludes } }, service=[myservice] ) 'elp! Pleeeez!

I'm going to try to guess what the problem is, but it is a little hard to tell from here. py2exe does its best to find all the modules required to create the ..exe. Sometimes modules do dynamic imports, etc. of modules that "fool" py2exe. I'm guessing that this is the case and that you will need to manually include the missing module. Most such errors seem to fall into this category. Hope this at least points you in the correct direction. -Larry Bates

To ask the obvious: do you have a pythoncom.CoInitialize () somewhere in your code? This is a bit invisible, because Services are inherently threaded, while you were probably running it before unthreaded. May not be the answer, but worth a try.

Maybe another possibility is that py2exe fails to include makepy generated modules. Could that lead to this error? Thomas

Could that lead to this error? Could easily be. I vaguely remember some similar problem with the WMI module, which I worked around by not doing a dynamic import in the end... or something. Don't think I've got the option here. (I wrote the active_directory module, in case it wasn't clear).
