I am trying to use 3 virtual server(application, web, and Database) to setup a web application system.

And when I usig application server to Dtc ping the Database server it return me this error:

Problem:fail to invoke remote RPC method
Error(0x6D9) at dtcping.cpp @303
-->RPC pinging exception
-->1753(There are no more endpoints available from the endpoint mapper.)
RPC test failed


I am already tried all teh method which mention in microsoft support site
"http://support.microsoft.com/kb/839880"

But the problem is still persist.

Does it mean that, virtual server is unable joining to setup an application?

I am hitting wall here, I am already research a lot about tis problem.


Any help is much appreciated. Thank you
