AG listener creation failed SQL Server I'm getting the error below while creating an AG listener in SQL Server.


  Ensure that the network adapters for dependent IP address resources have access to at least one DNS server. Alternatively, enable NetBIOS for dependent IP addresses.


The user has full privileges and it can create a computer object and a DNS entry successfully.

Please help me to fix this issue.
First, make sure the cluster's user account can create computer objects in Active Directory. See this link for the specific steps you need to do in Active Directory Users and Computers to grant the permissions. By default, the cluster does NOT have the rights it needs and the AG wizard doesn't really do anything to warn you or to grant those rights for you.
