Resolving an Error When Creating an Availability Group Listener

Resolving an Error When Creating an Availability Group Listener.

In this post, I’m going to talk an issue that I found when creating an Availability Group (AG) listener by using SQL Server Management Studio's Add Listener dialog box, you may receive below error message that includes information about the cause of the error, which can help you to resolve the issue.
The WSFC cluster could not bring the Network Name resource with DNS name '<DNS name>' online. The DNS name may have been taken or have a conflict with existing name services, or the WSFC cluster service may not be running or may be inaccessible. Use a different DNS name to resolve name conflicts, or check the WSFC cluster log for more information.
The attempt to create the network name and IP address for the listener failed. The WSFC service may not be running or may be inaccessible in its current state, or the values provided for the network name and IP address may be incorrect. Check the state of the WSFC cluster and validate the network name and IP address with the network administrator.
