I am System Administrator, I need to Keep All users as a Standard user access in all windows 7 pc but I want to give priviledge to user change tcp / ip so how it can possible.

Not directly. If user have this priviledge just after he/she logs in, then you can create scheduled task with elevated rights and SYSTEM that runs ncpa.cpl. Regards Milos

Hi, I suggest you add these users to Network Configuration Operators group so that they can change the TCP/IP without admin priviledge. Use the Network Configuration Operators group http://technet.microsoft.com/en-us/library/cc754921(v=ws.10).aspx A Description of the Network Configuration Operators Group http://support.microsoft.com/kb/297938 Hope this helps Vincent Wang TechNet Community Support
