I had the problem that after moving a network share in the cluster to another node, access to the disk via Windows Explorer always ended up with an "Access is denied".
Access to the disk via the CMD with elevated privileges was given, as well as over the network only not via Windows Explorer.
The solution was to deactivate the UAC.
Set-ItemProperty HKLM: \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ policies \ system -Name EnableLUA -Value 0
After a reboot I was able to access the disk via Windows Explorer.
