Download DTCPing on all computers involved in the distributed transaction and run it Check Application Server and Database Server are on same domain. Possible reasons are Computers are not reachable by NetBIOS name. In this case you either have to adjust their hosts file to add mappings IP/hostname or if in a domain add DNS aliases for them. The servers are VMs and they were cloned from the same VM instance. In this case the MSDTC CIDs are identical and you need to install/reinstall MSDTC (DTCping will tell you this).
