What changes, if any, to TCP/IP settings would require a reboot of a server or client machine ?

Considering the changing of Network adapter settings and when they are actually applied, expecially considering when to be certain that these settings have applied as a dependency for application testing.

On the windows TCP/IP settings , there are various levels of settings.

  1. TCP/IP properties - Static or DHCP ip And automatic or set DNS

  2. Advanced TCP/IP Settings - IP settings , DNS (append suffixes, append parent suffixes e.t.c.) , WINS

I am looking at this in the context of Windows Server 2012 R2 and later.

Do changes to any of these settings require a reboot to be effective ?

If so , which changes in particular require reboot?

If no reboot is required, excuding app restarts which I would do anyway, do we require any OS specific commands to be sure ? (e.g. flushdns e.t.c. )

Kind regards,
Junaid

No reboot required. If the server were a domain controller then I'd do ipconfig /flushdns, ipconfig /registerdns, restart the netlogon service.

Hi,
In my opinion, you do not need reboot.
By resetting your network configuration, run as administrator to start Command Prompt, run the following commands one by one: ipconfig /release> ipconfig /renew> ipconfig /flushdns. After running these commands, your network configuration will reset.
