Probably a virus on one of the clients. Find out what IP address the traffic
that is hitting the ISA Server is coming from and clean the virus from that
machine.
w32/nachi causes traffic like this.

Yes we have done this. We have noticed also terminal services no longer
works. But today we did something. We disabled all the users accessing
the internet and all of a sudden terminal services began to work and the
internet became very fast.
We are also noticing outbound traffic is massive. This maybe due to
virus?
Any chance of cleaning inbound and outbound ISA traffic?

Have you run Performance Monitor to see how your CPU, memory, disk usage
and network (for basics) are doing?

HI
We have had ISA Server 2000 running for around 7 months with no trouble
at all. We know we have set this up correctly and are happy with th way
it has been running with around 50 users. Since August 2003 we have
added around 150 users, bring the total number of users up to 200 users.
Everything has been running fine since, up until 5 days ago. All the
users have seen a massive slowdown in internet speed. We have an 8MB
line to the internet so we know its not lack of bandwidth, even though
we have heavy web traffic. We were very confused because another one of
our sites which is much smaller had exactly the problem at the same
time, but thismay just be a coincidence. Since then we have found that
making the users install a firewall client and asking them to enable
"Use a proxy server for your LAN", in LAN Settings under Internet
options has improved the speed of the internet dramatically bringing the
services back to normal.
Our ISA setup is basic, as we are not in a corporate network. So there
is no domain, etc. But our ISA config is a little more complex, with MSN
and KAzaa enabled but restricted to useonly a percentage of the
bandwidth, but i dont see this as the problem as it has always been
there and has been used.
Can anyone shed light on what can be causing the problem?
Regards
Sachin
