Group policy for changing binding order of network adapters

Question

Hi,
We have enabled Wifi and Wired (LAN) connections at the same time for users using group policy. Both connections works properly on laptops. Now some applications are not working due to routing issues as same connections are working at the same time.
We want to change connections priority in such a way that Wired (LAN) should always take priority over WiFi connections.
http://support.microsoft.com/kb/894564 describes method for changing same on single computer.
Can this be achieved using group policy.

Hi,
There is no corresponding group policy settings which can change binding order of NIC. However, in the article you provided, it says that we can create a fixed metric by changing
the InterfaceMetric registry value or set the interface metric by using a script. In this way, we can choose to use Group Policy Preferences Registry extension to deploy the registry change to clients, or we can use group policy to deploy the script to clients.
Regarding GPP registry extension, the following article can be referred to for more information.

If we choose to deploy script via group policy, we can assign computer startup script or user logon script.
Regarding this point, the following article can be referred to for more information.
