ASDAN Online Assessments on Windows 7
We've just started using ASDAN Online Assessments and is currently working well...on Windows XP however when starting the application on Windows 7 I get the message "It seems that this workstation is using a Proxy Server to connect to the Internet...." The address/IP address has been added to my proxy server bypass list and the upstream firewall has already been configured to allow traffic through on ports 80 & 443 for asdanonline.org.uk so isn't getting blocked.
All GPOs applied are the also applied to the Windows XP computers and both are using IE8. I've even tested this on a vanilla non-domain joined computer with no proxy server defined yet still get this error.
I'm struggling to understand why at my site this works fine on XP but not on both domain or workgroup Windows 7 computers.
