DCOM got error "The RPC server is unavailable. on Windows 2008 - Resolved RRS feed

  • Question

  • Hope this will help others having "RPC server is unavailable error" on Windows 2008 R2 server.

    1) Try to set up simple DCOM server/client on the servers in question.


    Ensure that it throws the same error message as your client application.

    2) On Windows 2008 R2, setting up new firewall rules for Incoming DCOM would actually resolve the issue. See this article on how to set up.


    Just by adding "COM+ Network Access" application role may not be sufficient on Windows 2008 R2 servers.
