Ah! For this you need another trick, at least I solve this problem with a trick, not sure if there is a better way.

What I did was creating a Proxy Object which only mission is to return the running COM using GetObject (for this you need to solve the GetObject bug as pointed out earlier), this is an schematic of what I did:

[Computer 1 (Server)]   [Computer 2 (Client)]

myDCOM                  Create an Instance of myProxy in Computer 1 and thru it get a reference of the running myDCOM (Using CreateObject)
myProxy
----------------------------------------------------------------------------------------------------------------------

myProxy has only one method called getMyDCOM() that will make the actual call to GetObject(, 'myDCOM.Application')

In this way I am able to grab an instance of a COM object that is already running in a remote computer
