I'm running Active Directory on Windows Server 2003. We recently implemented Cymphonix - Network Composer. We are pushing all web traffic through the Cymphonix Proxy to black list certain websites, track web usage, etc.
Our current problem is that we control access to certain parts of our Intranet by using the "Integrated Windows Authentication" option in IIS on the Intranet Server. Since all traffic is coming from the Proxy Server this authentication is lost.
I need to create a GPO to add our Intranet web address in the Proxy Exclusion list within Internet Explorer (Internet Options > Connections tav > LAN Settings > Advanced > Exceptions). Can someone advise how to do this please and how to set this up for a test group initially before deploying to my entire organization?
