Luke,

Thanks for jumping in but actually this is not ultimately what solved the
problem. I finally had to open a case and use one of my tech support
incidents with the ISA Server group.

The solution was to create allow packet filters for port 80 and 433. The
reason is that nothing can get out on an ISA box unless there is a packet
filter for it. For clients not on the box, there is NAT, proxy or the
firewall service itself but the problem arises when you are on the actual
ISA box itself and try to do something.

Thank you for your willingness to help.

Mike
