Hi everyone, 

I am going crazy trying to figure out what is happening with ISA 2004 EE.
From a fresh reboot, you get about 24 hours of good service and then it
stops responding to web proxy requests from internal clients.

Incomming traffic continues to work fine and even some clients (FW Client)
continue to work but within about 10 or 15 minutes, ISA will stop
respondig to everyone for web access.

You can not restart the FW service as it will not stop. 

I have captured packets from a client while the problem is happening and
what you see is the conversation start with ISA, the request for say
google.com goes out to it, ISA responds with a keep alive and then nothing
happens after that.

The only way to fix the problem, (for another 24 hours) is to reboot it. 

Has anyone seen this happen? any advice on troubleshooting? This is
becomming a rather urgent problem...

Thanks
