Sharing and friendly reminder for myself as I will for sure run into this problem again in the future.
When creating a Windows Failover Cluster, you get this error message (btw, did you know you can Ctrl+C copy the text from a dialog box and paste like this);
The operation has failed.
An error was encountered while loading the network topology.
Error Code: 0x80070005
Access is denied
Solution: In this case I had to remove the User Account from AD’s “Protected Users” group because Failover Cluster is still using NTLM and CredSSP. Relogon and it’s now possible to create the cluster, and then just add the user back into the Protected Users Group.
