Lync Server 2013: Unable to publish Topology, trouble with trusted servers (lync Migration 2010 to 2013)

Today, when i was publishing the topology from the Lync 2013 topology builder i experienced the following error message and the operation failed:

Error: A trusted server with the type “” and the fully qualified domain name (FQDN) “” was found for a different Transport Layer Security (TLS) target


Solution
Do the following to resolve this issue.
  • Open ADSIedit
  • Navigate to Configuration > CN=Services > CN=RTC Service > CN=Trusted Services
  • Right click an entry and select properties
  • type: “msr”
    • to find the Lync entries
  • See if this is the service refered to in the error message
  • Delete each entry concerning your trusted server, make sure it matches type and portnumber
    • for me it was three entries

    • Go back to the topology builder and publish the topology again
    • Now see that this was successful
    • Go back to ADSI edit and see that the trusted server entries has been recreated
      • press F5 till all entries are there, may take a few minute
