Increasing connection speed of COm Object

I have an administration app that communicates to other PC's via COM. When
I execute a CreateRemote('Computer') and the remote computer doesn't
respond, I still get a iUnknown pointer from the command. It takes approx 2
minutes to "time out".

Q1 How can I determine if the remote computer iUnknown pointer is legit?
Q2 How can I make it time out quicker?
Q3 I can Ping the remote rather quickly -- How can I speed up the
CreateRemote Call?

Thanks

Jim

Re:Increasing connection speed of COm Object

Try running DCOMCNFG on server and client and set the primary protocol to
TCP/IP. Other than that, any delays is usually caused by the time it takes
to authenticate a domain account against a potentially remote domain server.
