A user (lets call him Peter) in our domain cannot activate a given COM component. Other users on the same client are allowed to this. Peter is not allowed to do this from other clients, too.
The error log shows this message (in German):
DistributedCOM:
Durch die Berechtigungseinstellungen (application-specific) wird der SID (S-1-5-21-2673674691-2724651309-2952049826-1211) für Benutzer BBC\guenther.weerts von Adresse LocalHost (Using LRPC) keine Berechtigung zum Activation (Local) für die COM-Serveranwendung mit CLSID

gewährt.
Roughtly translated: By the right configuration (app specifc) the SID (...) for user .... from address localhost (using LRPC) has no rights to activate (local) for the com application with clasid ... and appid ....
Any Ideas where to look?
