Hello to all. I am looking for a good guide on setting up isa for the first time. I would like to be able to cache websites. If anyone now of a good guide out there place let me know.
 
Configuring ISA Server 2000 (2004 ?) Snygress Publishing..
and isaserver.org as mentioned above...
 
Hope you don't mind me jumping in.

I am finding conflicting info on setting up ISA 2004, some docs tell me to configure the firewall to allow the DHCP server on ISA so that clients can collect IP info. I already have a DHCP server on my Active Directory network that I really don't want to disturb, do I have to install DHCP on the ISA box or can i continue with my own?

Thanks.
 
Also we have a trusted DNS server on our WAN that I want our internal DNS server to forward requests to (it does currently but we're about to put ISA in between), can I set the firewall to allow this or do I "have" to install a caching only DNS server on the ISA box for my DNS server to forward requests too.

Thanks.
 
ISA will use your existing DHCP server.

As long as outbound DNS queries (port 53 I think?) are allowed, it will work fine. If you leave the default outbound rule in place, it will allow it.

Excellent i've had quite a bit of success so far, i've created a few policies e.g. HTTP and POP filtering. The problem i'm now having is making the user groups feature work, my policies work for 'All Users' but if i try to add a group e.g. 'Email Users' and remove 'all users' it fails.

Does it require the firewall client to use these features?

Thanks.

 
Assumptions:
1. you have ISA running on a member server of a domain running active directory.
2. you're using AD's groups.
3. you have ISA SP1 installed

I haven't had any problems using groups to restrict access, etc. I have noticed that I sometimes have to restart the services for changes to take effect.

Are you getting any errors in the event log?

My appoligies.

I'm in a 2003 AD domain and the ISA is a member server running ISA 2004. I've setup DNS now and it works fine.

I don't receive any errors it's odd the rules work fine if i include all users i can turn protocols on and off at will, the problem is that as soon as i add another group and remove all users then noone can access the internet. Does it require the firewall client to be installed?

Thanks.
