Ok, I have this confusing problem with group policy and loopback enabled.
I have the following SBS network; SBS2011, Server 2012 acting as RDP server.
I would like to limit internet access on the RDP server with a fictitious proxy IP address whilst allowing select sites in the allow list. ( I set the proxy to 127.0.0.1, and added *Microsoft* in the exception).
I tested the above scenario on a Windows 7 machine and it works fine.
The RDP server is in the default container 'Servers' by itself, users are in their default containers also.
I made separate GPO's for Loopback merge and replace, I also made a separate GPO for limiting access to a Terminal Server(containing the proxy settings).
I have not modified any of the default shipped GPO's. ( As I was taught)
All other group policies like drive mapping etc... work fine.
Please see attached GPO tree...
I have never used loopback before so have done a lot of reading( I thought I had this under wraps - but obviously not)
Can someone please help me make this work - SO frustrating.
There is another post on EE - where this scenario was not solved...
