Client to Server MSDTC connectivity Issues - Need help interpretting DTCPing results

    Question

  • Working on getting MSDTC to work between Windows 7 SP1 and SQL 2008R2 server SP2. Both client and server can ping each other by NetBIOS name. Both are part of the same domain.

    Running DTCPing getting a couple of erros before it fails. Having no luck resolving this.

    Server log reads as follows:
