Currently, DCOM on a Win32 system cannot talk to DCOM on other systems, such as VMS.
On a Win32 system, the DCOM Service Control Manager (SCM) or resolver always listens on the same endpoint as the Remote Procedure Call (RPC) endpoint mapper (that is, port 135). On foreign systems like VMS, the DCOM SCM or resolver may listen on ports other than 135. When a Win32 DCOM system tries to connect to the foreign DCOM system by using RPC, it must take this into account. If a Win32 DCOM system cannot find the DCOM SCM interfaces on port 135, it must fall back to talk to the endpoint mapper on the foreign system and find the endpoint on which the foreign system listens. DCOM does not do this correctly for Object Exporter Identifier (OXID) pings.
To resolve this problem, obtain Microsoft COM+ Rollup Hotfix 22.
