I have one domain 2008 R2 split across two sites. Each site has its own proxy server for internet access. Each site has its own dhcp server. Question is, how do I get the users logging on to site 2 to use their own proxy server via group policy. At the moment all users are in one OU and so the GPO that specifies the proxy server is applied to all users. Is there any way for group policy to check IP address for example and then apply a different setting?
