RE: ISA DNS server

I too have had DNS cache problems. The firewall service does have a
builtin cache that is used for all Firewall client machines. The only
way Ive been able to get round it is to either restart the firewall
service, or disable the firewall client and flush the local dns cache on
the workstation.

Actually ISA does have its own internal dns cache.  Have a look at
http://www.isaserver.org/tutorials/ISA_Clients__Part_1__General_ISA_Serv
er_Configuration.html toward the bottom of the article (underneath the
last screenshot, the "Web Proxy and Firewall DNS Cache" bullet.

No it does not. What you probably saw reference to was setting up the
DNS service on the ISA server and using that for lookups.
