The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process

Hi

I am in the middle of migrating from exchange 2003 to Exchange 2010 online (Office 365)

I am running the Remote Connectivity Analyzer (www.testexchangeconnectivity.com) and getting all passes until the bottom when I get the error in the attachment.

Ive scoured the net and found places that tell you to test via telnet (this all works) and also add registry edits to all Global Catalogs (which I have done) but I still get the error message.

I have 2 Global Catalogs (a 2003 DC and a 2008 Application Server)

I cant continue until this is fixed, can anyone help?

Kind regards

Andrew

I resolved the solution by removing a currently tombstoned Windows 2000 domain controller.
Then the RPC connection was established successfully.

Just an observation but I have read the link referred by Rajkumar. There is no resolution there just a workaround that does not actually solve the problem.
