Technical Solution



When using 802.1x Network Access Control in Transparent mode the Symantec Endpoint Protection (SEP) 11.0 client may stop certain Windows services which are required for connecting to a wireless network, in order that SEP may be used as the only supplicant on the machine.
This causes problems when attempting to use one NAC Enforced wired connection and one non-Enforced wireless connection from the same machine.

The following options are enabled in the Symantec Endpoint Protection Manager:

  • Enable 802.1x authentication
  • Use the client as an 802.1x supplicant
  • Use Symantec Transparent Mode

The Windows services that are stopped by the SEP client are:

  • Wireless Zero Configuration (XP SP2, XP SP3)
  • Wired AutoConfig (XP SP3, Vista)
  • WLAN Autoconfig (Vista)



This issue has been resolved in the MR4 release of the Symantec Endpoint Protection product. After upgrading to the MR4 release the Windows services will no longer be stopped by the SEP client.
