(Ref. MSDN Q259011)
The DCOMTEST program pair is based on the simple DCOM sample provided with the 
platform SDK.

In what way it is different I don't know but it is basically the same.

As far as we are concerned the first stumbling block is a call to

To get anywhere you will need to use the native ole32.
