How to Start/Stop Wired AutoConfig service

Description:

The Wired AutoConfig (DOT3SVC) service is responsible for performing IEEE 802.1X authentification on Ethernet interfaces. If your

Layer 2 connectivity and/or providing access to network resources. Wired networks that do not enforce 802.1X authentication are
unaffected by the DOT3SVC service.
