Hi All,

I got ISA 2004 as a proxy server to our network. Users keep complaining that Internet is very slow through the Proxy. I got 10MB Internet link and
without proxy is very fast.

I have noticed my Cache Drive is fragmented  and can not do any defragment?
got 25GB free space.

Have you correctly deployed the ISA Firewall?

Internal and External interface?

Correct DNS settings on the ISA Firewall's interfaces?

Remember, the ISA Firewall is always a firewall, and you're treating it as a Web proxy only may be leading to configuration problems.

There are a number of things that could be going on as Dr. Shinder mentioned. You have to do a bit of research before we can be of much assistance. Below is a link to the MS troubleshooting page. It has saved me a time or two. Take a look at the performance monitoring section. This may help.

Also... When in doubt think basic and go back to an ISA 2004 book and review your configuration from the ground up.
