RPC is a Windows Service you will find running on any windows machine. It provides the machinery for doing remote procedure calls. You may have heard of COM (Component Object Model) and OLE (Object Linking and Embedding). These are means of communicating between applications, for instance your application and Microsoft Word. These use RPC as the way to implement that communication. For RPC purposes your application calling on Word to do something is the client and Word is the server. This is also referred to as 'Automation'.

You are in some sense 'automating' Word via your application. In the end, both your application and Word will be using RPC at some level to communicate.

To accomplish this, the application establishes a connection to the server using OLE or COM. That connection stays alive while it's being used and is shut down when you are finished. When you get the 'RPC server unavailable' error under these circumstances it means that the connection was lost somehow. I have complete access to the application code and DLL code..it was custom written by me to do Word automation.

All of the code is in C#. By the way.the problem seems..SEEMS. To have cleared itself up.atleast for the time being. Tell me more about QueryInterface( ).

I thought it was used to expose PUBLIC methods to a potential consumer of a COM object. But you say it can also report as to the availability of the COM object in general? I am a COM noobie.as you can tell.

I have a good book on.NET and COM written by Adam Nathan at Microsoft. Perhaps it talks about RPC?

'QueryInterface( ). I thought it was used to expose PUBLIC methods to a potential consumer of a COM object.' That's correct. You call it to ask a COM server for an interface that you are interested in. If it succeeds, you can use the interface further. If not, what you are interested in isn't available. Perhaps it's not implemented in that server.

Checking for the availability of a COM ojbect is general is a bit trickier. You might call CLSIDFromProgID() with the programmatic name of the COM object you are looking for and it would return you a class ID as a GUID. That tells you the object is at least in the registry.
