The Wired AutoConfig (DOT3SVC) service is responsible for performing IEEE 802.1X authentication 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.

The Wired AutoConfig service runs as localSystem in a shared process. It shares an executable file with other services. If the Wired AutoConfig fails to load or initialize, the error is recorded into the Event Log. Windows 7 startup should proceed, but a message box is displayed informing you that the dot3svc service has failed to start.
Wired AutoConfig will not start, if the following services are stopped or disabled:
