Problem listing services with wmi

Seems like your hunch was right, the first loop completes correctly. 
Adding a counter to both loops shows that getting services from 
win32service.EnumServicesStatus() gets 108 services, and getting them 
through WMI gets to 87 and then halts with the previously mentioned error :

Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "G:\Python-2.4\Lib\site-packages\win32com\client\util.py", line 
83, in next
    return _get_good_object_(self._iter_.next())
pywintypes.com_error: (-2147217398, 'OLE error 0x8004100a', None, None)

 From examining your code I imagine you tried to catch the exception, 
but it didn't work because the exception is thrown on the "for" line and 
not when getting the service's Caption property... So it stopped at 87 
anyways. And indeed, the "only in win32" list shows 21 entries ( 
len(win32_names - wmi_names) = 108-87 = 21 ).

Python 2.4 on Windows XP SP2 here.

Do you think we're getting anywhere with this? If not, then I'll just 
use the "win32" method of getting the service list, even though it isn't 
as pretty. I don't want to waste your time on something that may have 
more to do with my machine than anything else... But if you want to try 
and get to the bottom of this, I have no problem with trying out other 
suggestions.

Thanks a lot, just by your small scripts I've already learned a lot more 
about Python!
