SYMPTOMS
When you have a COM+ server package that allows anonymous authentication and you subscribe to the IComSecurityEvents interface, the COM+ application may experience failfast.

Assertion Failure:

psidDirect

CAUSE
This issue occurs because you cannot obtain the DirectCaller security identity or the OriginalCaller security identity, and therefore you try to impersonate the client.
