Q: tool for switching NIC status on off on windows is there a tool that can turn on/off (enable, disable) an NIC interface on windows OS?
thanks in advance.

A: Crack open a cmd.exe window and do the following:
netsh interface set interface "Name of Interface" ENABLE
OR
netsh interface set interface "Name of Interface" DISABLE

A: found this MS utility that can enable, disable, restart and query individual devices or groups of devices
