Thanks guys! :o)

It seems that no module is missing since the Service starts and the
error message seem to indicate an error in the COM call to the AD.
I would expect some other exception..

I do have a separate thread for the asyncore.loop() as I otherwise
would risk a lockup.

I do not call pythoncom.CoInitialize () as I tend to expect a module
wrapping COM stuff to do that. Since I am not really into Windows, I
have to ask you, do I make a wrong assumption here?

Some further info that may be of interest:
python 2.4.3
active_directory 0.4
py2exe 0.6.5
pywin32 208
The Service code is taken from MyService.py supplied with py2exe as a
sample.

Hmmm. A slightly philosophical point. As the author of
the said module, I think I'd have said that the other
way round: I do not call CoInit... because I expect a
user of the module *who needs to involve threading*
to do that. However, I'm quite happy to call it willy-nilly
as long as there's no overhead. But I'm afraid my
knowledge of the interaction of COM with threading
is slim and mostly anecdotal.

All that looks good enough.

Is it possible for you to include the CoInit... call
anyway, simply as a test to see if it is the problem..
It might not be, in which case the point is moot.
(At least in this case)

If you don't get much help on this list, might
be worth moving the discussion over to the python-win32
list. I'm sure many people (like myself) watch both, but
there may be some who don't follow this list, but
do watch the -- lower traffic -- win32 list.

:o) I agree!

I have added the CoInit.. call to the __init__() of the threaded class
(I understood the documentation as that was a proper place.)
The exception message changed!
Unfortunately I get little wiser.. (yes I confess.. I am spoonfed with
unix ;o)

OK. Now we're into the ClassID thing. I'm hoping that someone with
py2exe knowhow will chip in here. That line is trying to generate
a Python module to correspond to the ADODB.Command typelib:

command = EnsureDispatch ("ADODB.Command")

The py2exe wiki suggests that a slight nudge to the code
might fix the problem:

http://www.py2exe.org/index.cgi/IncludingTypelibs

At this point there are several options open to us:

(in no particular order)
1) You could nudge the code at line 217 to make use of
that suggestion.
2) I could do that and send you the result.
3) I could alter the module so it doesn't use gencache
at all. I don't seem to be using any constants so the
Dispatch might as well be dynamic.
4) None of the above.

I'm happy to do (3) and send it to you privately if you're
willing to try. Of course, it might not be the cause
of the problem in any case!

Really appreciate!
Reading the page you indicate, I tried solution 3 as it seemed to be
the favored one by the author.. I simply added the lines, doing the
import and the setting the flag, in a copy of the active_directory
module.
But maybe you thought of some other nudging?
Some kind of progress anyway, I guess (see below).
Maybe your offer to do your option (3) is worthwhile after all?
