Cluster aware updating cancelled issues with object removal and server manager refresh

Question

Hello,

I was installing Cluster-aware updating (incorrectly) in my new Failover cluster and had to cancel during the install and now I have a computer object thats causing my Server manager to fail refresh. I've deleted the object from AD but its still showing up in Server manager in all servers no matter how many times I remove it. I've tried to run (cd C:\Windows\System32\wbem\Autorecover then running  for /f %s in ('dir /b *.mof *.mfl') do mofcomp %s) but that did not help and the CAUAnnex5fe8jyb is still showing up. I have tried the registry hack too but it just changed back to 1. If I try to run the command to remove the Cluster aware updating it just fails and says one does not exist so I cancelled it in the worst time. I am hoping someone can help me out here. I have 4 servers that will not refresh because they cannot contact CAUAnnex5fe8jyb because it does not exist!

Thank you!

Scott

Hello

For this purpose you may need to use the Remove-CauClusterRole cmdlet to specifically tell the cluster to remove the member, even if the object was deleted positively from AD.
