All works good long time about 2-3 months. But sometimes it happens...
Firewall clients on workstations don't see
ISA server, but protocol http works right, web sites are opened. ISA server normally works too. After restarting firewall service on ISA all works good. In event logs nothing bad, all as usually.
Where may be error? What I can do for begin tracing?

Same thing over here.

Everything worked fine for months.. But now every few hours the fwclient is unable to access the isa server. error message is something like: "unsupported client version" blabla. Restarting the firewall service helps at once. Waiting a few minutes without restarting the fwsvc sometimes does help too...

No idea what happened.. I did install Win2kSP3, maybe that's the prob :-(

Also, shouldn't Service Pack 1 handle this issue?

Thanks!

Don't know. The problem reappeared after my machine was up for a longer time :-(
Just after restarting it, the chkwsp32 tool gives an "Everything fine" and after a while the problem appears again :-(

I wrote a Mail to the internal MS ISA-Discussion Group. Maybe some of the guys have an answer to this question.

I solve my problem! (first topic) One user downloaded very big file (1,5 Gb) from our branch office throw isa server. We see that on DMZ by sniffer.
Is there method to see that on ISA server?

Have you tried GFI ISA Monitor ???

It's free and shows you all current connections...

Are you able to successfully connect after restarting the service? This is one of the problems we were seing the other day. I was forced to rebuild the server to get it corrected. I would be very curious what MS has to say about this since there seems to be a rash of these issues over the past week.
