CAU - Target name resolution error

If removal of the CAU for a Windows Server 2012 R2 Failover Cluster has failed or if anyone has tried manually clean up the CAU, the following error might appear in Server Manager.


 
 
A look in the logs shows...:
 
Log Name: System

Event ID: 10028
Level: Error

"DCOM was unable to communicate with the computer CAU-name.domain.local using any of the configured protocols; requested by PID b54 (C:\Windows\system32\ServerManager.exe)."
 
 

....and/or:
 
Log Name: System
Source: FailoverClustering
Event ID: 1228

"Cluster network name resource "CAU-name" encountered an error enabling the network name on this node. The reason for the failure was:
"Unable to obtain a logon token"
 
The error code was "1326".
 
You may take the network name resource offline and online again to retry."
 
 
If you do not see any trace of CAU but still see these error messages is probably the reason that CAU's Distributed Network Name is left lying around in the Failover Cluster. CAU's Distributed Network Name will be added up automatically during configuration of CAU but does not appear in the Failover Cluster Manager, but is hidden. Use PowerShell to list Cluster Resources and you will see the CAU's Distributed Network Name.
 
  1. Open an elevated Powershell window
  2. Specify Get-ClusterResource -Cluster "Cluster Name"
  3. Remove-ClusterResource "Name"

  2. Hi Hildebrant,

    Did you run Powershell as an administrator when you tried that?
