access problem with DCOM server written in python

[Achim Domma (Procoders)]

Hi,
I have a problem with a DCOM server written in python. Here is my 
minimal test object:

class TestObject:
    _reg_clsid_ = "{ECDBB3BC-F0BF-4eef-87C0-D179A928DAB5}"
    _reg_progid_ = "DComTest.Object"
    _reg_desc_ = "DComTest.Object"
    _public_methods_ = ['testit']
    def __init__(self):
        pass
    def testit(self): pass
if __name__=='__main__':
    #   register object
    from win32com.server.register import UseCommandLine
    UseCommandLine(TestObject)
The object is registered on server S and on client C. The user U exists 
on both machines with the same password. Accessing 'normal' C++ COM 
objects from C on S works fine, which means the DCOM is working at all.

U is able to create the object localy, but accessing my test object via 
DCOM gives me an 'access denied'. I used dcomcnfg to grand U the right 
to start and access the object on S (same settings as for working C++ 
objects), but I still get 'access denied'.

The server was newly setup. The script was working on another setup, but 
I have no idea what might be the differnce.

BTW: Accessing the object with an admin account works just fine.
Any hint on how to solve, or at least debug, the problem?
regards,
Achim
