When I see that is my pipe is getting full, I check my TrafMeter. Thanks for
the link Tom !
It's a great deal for monitoring your link's usage. Also a great help for
configuring ISA's bandwidth policies.
It's definitely worth its 50 bucks. www.trafmeter.com

But why Tom, why disable the HTTP redirector? Can you say that in public? ;)

Hi Glenn,
You might want to run NetMon on the external interface and check the packet
filter logs to see if you're being attacked. It could be that the T1 is just
pegged.
Make sure your Web Proxy clients are configured to use the autoconfiguration
script and that DNS server settings on the ISA firewall are correct. And while
not required, I highly recommend disabling the HTTP redirector (for perfomance
and security reasons).
HTH,
Tom

Thanks Tom for the valued input, I am working out a performance issue I am
having with my ISA server right now, My CEO is complaining loudly about poor
performance
I have monitored the ISA server using Performance Monitor, selecting just about
everything one could monitor, including the Physical Interfaces, as far as I
can see,
the ISA server is NOT over loaded, but the External Interface seems to be
peeked out all the time, it is a 100 MB PCI interface plugged into a 3COM 3300
Switch,
The computer is a Dell Power Edge 2300, I know, rather old but it does have
DUAL PII 400 Processors and 512 MB RAM ... From what I can see using
Performance Monitor, the ISA Services, Firewall and Web Proxy are idling but
the External Interface seems to be pegged ?? Any suggestions ? It is worth
noting that my ISA server also has 4 RRAS L2TP VPN Tunnels connecting my 4
Branch offices, I did add and monitor all my VPN connections and they don't
seem to be over loaded, it just seems to be my External Interface? I still
have my OLD Raptor firewall, so I decided to route some users through it for
performance comparison and the sites come up lightening quick, through ISA,
they take forever?
