Wired AutoConfig

 

Windows 8

Default Description

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.

Additional Information

None at this time.

Additional Information

I include this service in the following group of services:

WLAN AutoConfig, if set to Manual, will not start automatically if you use a hardware switch (such as those on laptops to turn on and off the wireless network card). If you require wireless connectivity on your computer, keep the listed services above on the default values as well as place WLAN AutoConfig into Automatic. If you do not have a wireless card installed on the system, or do not require authentication on your wired network card, the group of services can safely be disabled.
