COM+ remoting error code 8000401a because password of This User under Identity tab getting reset

Question

I am an admin in my COM+ server machine, my COM+ server component identity set to "This User" and provided my credentials there. I could invoke my component from client machine. But client app will stop working after some time with errorcode 8000401a. So I shutdown my server app and when I start the app back it shows an error username and password incorrect with error code 8000401a. When I re-entery my password again and strat it back. it works fine. Seems my password entered in identity tab is being reset? Why?

Answer 1

The short answer is that your domain account looses its Log on as a batch job privilege on every Active Directory resync and the server app is unable to restart afterwards. Re-entering your credentials restores the privilege only temporarily.

You have to permanently give the Log on as a batch job privilege to your account via the GPO on the domain controler (see Q312497 for the complete description).

I'm not sure why, but I've had a case where the Log on as a service privilege was also required (try that as well if the Log on as a batch job doesn't do it).
