Lost Internet on a remote Windows?

Question

Windows

On a remote server there is Windows10, on which the program I need is running, I go to it through RealVNC. Recently, once every 3-4 days, access to the server began to disappear, I thought that the vnc server was crashing, I connected RDP and teamviewer. In another such case, when both realVNC and TeamViewer gave a connection error, I logged in normally through rdp and it turned out that there was no network connection anywhere, except through rdp, only restarting the server helps. How can be cured?

Answer 1

Find out the reason for the falling off the Internet - and eliminate it, obviously. Log-figogi, monitoring-figatoring.

Answer 2

Problem with DNS.
Incoming RDP connections don't care about DNS, so it worked.

Answer 3

How can be cured? I googled solutions like this:
netsh int ip reset
netsh winsock reset
ipconfig /flushdns
ipconfig /renew
But it doesn't help, it falls off stably every 3-4 days and you have to reboot
