I have got a COM server working as a service now. The only problem left is
security. If the service runs under my userid everything works fine, but if
I install the service as the local system user (i.e. the default) then
attempting to access the COM object throws a com error 'Access is denied'.
I'm not sure how to get round this. I can use DCOMCNFG to give access, but
I feel I should be able to set the security from inside the process.
Unfortunately I cannot find a combination of parameters to
pythoncom.CoInitializeSecurity that doesn't either complain 'obAuthSvc must
be None or an empty sequence' or GP fault (if I give it obAuthSvc set to
None if complains, if I give it an empty sequence it dies).
I'll post my minimal COM service when I have tidied it up a bit.
