Mike,

>I'd almost swear that DCOM servers can be DLLs that run within the DLLHOST.EXE process on the remote machine. In fact, I believe chapter 16 of the Programmer's Guide, to which I referred Bruce, illustrated how a DCOM DLL server runs in the process space of a proxy stub. I'll have to investigate tomorrow.

DLL's only run remotely if run by MTS.
