NLA Error Appears After Server Restart

Question

Hello,

We have three servers that I restart on a monthly basis to ensure they are running smoothly and to apply any updates that may require a reboot.

Occasionally, after a restart, of one server (Database server) I encounter an error message when attempting to log in remotely. The error states: "NLA error – Network Level Authentication."

The message: "The remote computer that you are trying to connect to requires Network Level Authentication (NLA), but your Windows domain controller cannot be connected to perform NLA, if you are an administration on the remote computer you can disable NLA by using the options on the remote tap the System Properties dialog box"

I'm trying to understand why this issue keeps recurring. It's worth noting that if I restart the server again, it usually resolves the problem and allows normal access.

Note: I have full administration privileges and a good network.

Thank you.
