We use an ISA server in Integrated mode. Anticipating a planned power outage we shut the server down. After restarting the server our users arent able to browse the web unless they have a proxy enabled in IE, before the restart all could browse through secure NAT. I've been looking for documents on 'How to disable Secure NAT web browsing' so I can do the reverse but havent had much luck. Any ideas? Iain.
