>I created a set of dlls that are working fine locally or remotely as long as I am the user, if someone else tries to use them, it also almost works perfectly, except a call to GETINTERFACE() that I have in one of the dlls fails with access denied. So, I tried to configure the DCOM to allow the access, but unfortunately the dll is not listed in the Component Service -> DCOM config, I tried to unregister all and rebuild them all, tried them as dll and exe, move them to System32, I think I tried everything but reboot my computer, but still the dlls do not appear in DCOM config, so, me thinks I am forgetting a very simple step?

Arghhh. Now they finally appeared in the DCOM config branch (I logged out/in) but it did not solve my problem.
