AlwaysOn AG Listener: The attempt to create the network name and IP address for the listener failed

While working on a heap of High Availability and Disaster Recovery solutions, I was challenged to deal with some complex errors that I had to overcome as fast as possible. Today’s post is going to show how we may solve one of them. I am speaking about the following error which is raised when we have to set up the AlwaysOn AG Listener:

The Windows Server Failover Clustering (WSFC) resource control API returned error code 5057.  The WSFC service may not be running or may not be accessible in its current state, or the specified arguments are invalid. 
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. (Microsoft SQL Server, Error: 41009)

At times it can be quite easy to fix it, but it may become complicated as we do not have more details of the root cause, therefore, it does not give us any clue. In my experience working on this, the most common cause has to be about lacking of permission for the cluster name account so we have to make sure that this account has the 'Create Computer' and 'Read' permissions:



Once you have given right permissions and if the error is still there then you must check whether the IP Address is available to be assigned to the AlwaysOn AG Listener. It is simple to verify by making ping to IP Address which should be free. If not, ask your Administrator a new IP Address and try again.
I hope this practical post helps you. Let me any remark you may have. Until next post, thanks for reading!
