Hi,

I have 2 domain controllers Windows Server standard 2008 and Windows Server 2012. Windows Server 2008 is primary domain controller while windows server 2012 is additional domain controller. Windows 7 professional is being used as client operating system. There are more than one thousand college student users. I have successfully implemented group policy and in my lab and also by linking one system over network. Group Policy is working fine over my lab pc. While it is not being pushed over the other client stations. 

I have major issue with proxy settings which are not being automatically implementing in students login. when I test over my lab pc it works fine. even if I uncheck proxy settings, after re login it comes automatically. While there is same settings of all like gateway, dhcp and dns. Kindly guide.
