Hello,
We are having intermittent issues with a Microsoft Windows Server 2008 R2 Standard x64 terminal server running as a HyperV VM, which sometimes hangs when users try to log in or off, with the message "Waiting for the user profile service" appearing on-screen. This happens even if you log onto the console session. The "loading circle" does not even continue to spin. We are unable to remote into it via any other computer when that happens, and it cannot be connected to via remote Computer Management to check which services or running or stopped, either.
I had read somewhere that this could be caused by IPv6, and that disabling it may solve the problem. We wondered if this was true and if there is any actually other fix besides simply disabling IPv6, as ideally we would like to not have to do this.
Grateful for any suggestions.
