Hi I have ISA 2004 under W2k3 sp2, with many firewalls rules and everything woks fine, I usually have to make changes in this rules for allowing access etc...one day ago I had changes and specific programs like Exchange stopped access to Internet, everything seems fine, rules, connectios, ISP etc...but nobody can't send mail. and we also had problems with other programs.
I restored a saved configuration and the problem was fixed. (With the same configuration)
I didn't change anything in the configuration I'm sure, only some access rules in the firewall, but suddenly the ISA was corrupted (the configuration) and the only way to fix is restoring a saved configuration.
This problem has happened to me twice, and I can fix it restoring a saved configuration.

I had a similar issue when I was making a change to the configuration. After applying I started having weird access denied messages. It was like my rules were not processing at all and going straight to the default access denied rule. I did the same...reapplied my settings from backup...and it worked like a charm again. I just chalked it up as one of those weird gremlins. I haven't had another issue since.
