You may see “A trusted server….” error while publishing Lync Server 2013 topology.
In my case, I was adding Archiving and Monitoring role in existing Lync environment and had never faced this issue before.
After searching and looking into the error, I observed this error is occurring because of some existing entries in Active Directory.
To resolve this issue, I followed the below steps.
Note: Please take your AD backup before playing with ADSI Edit or ask your AD expert to perform the same activity.
- Open ADSI Edit (adsiedit.msc)
- Open Configuration partition and navigate to CN=Services>CN=RTC Service>CN=Trusted Services.
- Go to the properties of each entry under “CN=Trusted Services”.
- Type “msrtc” to search the Lync attributes in the property.
- Cross verify “TrustedServiceType” and “TrustedServerFQDN” with the error.
- Close the property and delete the entry.
- Publish the topology.
- If you get the same error again with different TrustedServiceType, follow the same procedure one more time.
Finally, publish the topology 🙂
