SGD Through Microsoft ISA Problems

Hi All,

We have a problem were a remote site is using MS ISA2000 as the permitter gateway. People accessing our SGD server from this site have been running fine for months then recently it would appear that the ISA server may have been reconfigured to only allow web access to ISA authenticated users only. Now access to the SGD server is failing. Opening the Java Console i have found that the SGD Applet is unable to use Authenticated proxy server. Is this correct ? I have managed to emulate this in a test environment using MS ISA 2006 as well. Below is the output of the java console.

Your help would be much appreciate

Greg
