Since a few weeks it seems that my laptop, after being locked for a few minutes, will kill the network connection. Every time I return to my it after it being locked for a while, I see apps having to reconnect, or tasks that have failed because lack of network connectivity. It happens on both wired and wireless connections.

Is there a way to disable this behavior? I've looked in Windows power settings, and NIC settings, but haven't found anything.

I'm working on a Surface Pro 3 with Windows 10 version 1703 build 15063.413

This may be because of a "System unattended sleep timeout" setting that is normally hidden, and that causes a locked computer to sleep even when the "Sleep" setting is set to "Never".

See this answer to a similar question.

Per the link above, the System Unattended Sleep Timeout setting is made available in your power settings if you set the DWORD attribute of the following registry key to "2":

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0
