I have the sensors installed and working on both of my domain controllers (Server 2016), however, when I install the ADFS sensor on my ADFS server (also 2016) the service refuses to start. I get the following error. I have tried everything I can conceive, including deleting the instance and starting over, trying different accounts/credentials/formats (both the single label domain vs. the .com suffix format) to no avail. The error is as follows:

 

2021-03-18 20:22:05.6369 Error DomainNetworkCredentialsManager Microsoft.Tri.Infrastructure.ExtendedException: DomainControllerDnsNames is empty or not configured

Any help is greatly appreciated!

Solution
Go to the sensors tab in the MDI portal, click on the registered ADFS sensor, and add to the list a fully qualified DC name this sensor can contact to resolve AD entities. once you do that and press sav, within 10 min the sensor should overcome this error.

@Eli Ofek This resolved the issue! Thank you so much - I couldn't find anything online to help!
