Remove cluster aware updating
This would be done as follows, with a proxy called The Proxy. Internal that operates on TCP 80: netsh winhttp set proxy The Proxy. Internal:80 “ CAU will require a computer account that will be used by the cluster to create a HA role that enables the cluster to self-manage the orchestrated patching, even if the nodes of the cluster are being rebooted.The setup wizard does allow you to let the cluster create a computer account in Active Directory, but this will get some anonymous name.
Unfortunately System Center Configuration Manager does not support CAU yet.Windows Server 2012 (WS2012) introduced Cluster-Aware Updating (CAU) to allow each member of a cluster be paused, drained of highly available (HA) roles, patched, and rebooted in an orchestrated manner.Without CAU, you will probably be patching your clusters manually (which rarely happens), and in the case of Hyper-V clusters, CAU will leverage Live Migration to ensure that services have zero downtime.This also made me decide to deploy Windows 8 and now 8.1 as the default client OS.The fact that maintenance (it the Resume Key filter that makes this possible) can now happen during day time and patches can be done via Cluster Aware Updating is such a win-win for everyone it’s a no brainer. Even better, it’s continuous availability thanks to the Witness service!This error can also happen if the target service account password is different than what is configured on the Kerberos Key Distribution Center for that target service.
Ensure that the service on the server and the KDC are both configured to use the same password.
If the server name is not fully qualified, and the target domain "domain.local" is different from the client domain "domain.local" check if there are identically named server accounts in these two domains, or use the fully-qualified name to identify the server." The solution is quite simple but perhaps not obvious even though it's stated in the error message.
What you need to do is to add two SPN's to your CAU account.
"The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server "server name".
The target name used was HTTP/server_name.domain.local. This indicates that the server failed to decrypt the ticket provided by the client.
Take the time to create a prestaged computer account with a name that will mean something to you and your colleagues in a year’s time.
