| Description | ||||
| Multiple network connections can provide additional attack vectors to a system and must be limited. The "Minimize the number of simultaneous connections to the Internet or a Windows Domain" setting prevents systems from automatically establishing multiple connections. When both wired and wireless connections are available, for example, the less-preferred connection (typically wireless) will be disconnected. | ||||

Fix Text (F-22510r857187_fix)
The default behavior for "Minimize the number of simultaneous connections to the Internet or a Windows Domain" is "Enabled".
If this must be corrected, configure the policy value for Computer Configuration >> Administrative Templates >> Network >> Windows Connection Manager >> "Minimize the number of simultaneous connections to the Internet or a Windows Domain" to "Enabled".
Under "Options", set "Minimize Policy Options" to "3 = Prevent Wi-Fi When on Ethernet".
