User policies

My HP 7250 has three users set up on it, including the HP Administrator.

When it's been left switched on but with no users logged on for a few hours, the LAN and internet connection stop working. So when a user logs on, the LAN and internet connection do nothing.

As the administrator I can right click the LAN icon in the tray and click disable. Then go to Network connections and click enable. This starts the LAN and automatically the internet connection.

When a non administrator user logs on, the disable LAN option is greyed out, so the only option is either for me to log on and do the procedure, or simply to reboot the PC.

Where or how do I edit the policy that will enable the LAN disable option for non administator users?

I've opened the group policy editor and read a lot of the options in there but am not confident I'd alter the right thing.

Any pointers please...
Cheers,
Lee

 

That surely wouldn't account for the fact that the disable option is available from the administrator account but not from an ordinary user account....

 

No, the disable option is still greyed out.

Anyone any other ideas please?

 

Have followed those instructions but the disable option is still greyed out for the ordinary users.

Cheers
