We've run into an issue with remote users who have Windows XP SP3 and IE 6 using a proxy. This problem started last Thursday evening, Aug 25th, with certian users. Seems that the proxy, in IE 6, when trying to connect through NC 6.5R5 is using the loopback address for the proxy, therefore, never connects via NC. Users with IE 8 have no problem. Users that are NOT going through Time-Warner for their ISP, don't seem to have the problem either. However, we have found a few users not going through Time-Warner to have the problem as well. We've tested on many versions of NC, 6.3R4 - 7.1R3, and the problem is still there with IE 6 users. Before Aug 25th, everyone was able to connect. If we remove the proxy info from IE, it connects, but without the proxy pac file listed, they cannot access external resources. No changes reported from the proxy admin, no windows updates, no change to the IVE config. Personal firewall logs are clean. AV reports nothing blocked. I have a ticket open with Juniper, and an Advanced tech is as much confused as we are as to what the problem is. Any suggestions are welcome.
