How to Start/Stop Wired AutoConfig service

Service name: dot3svc

Display name: Wired AutoConfig


The Wired AutoConfig (DOT3SVC) service is responsible for performing IEEE 802.1X authentification on Ethernet interfaces. If your
current wired network deployment enforces 802.1X authentication, the DOT3SVC service should be configured to run for establishing
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.

Path to executable:

C:\Windows\system32\svchost.exe -k LocalSystemNetworkRestricted
