ISA server auto discovery - which is first? DHCP or DNS

I'm working on a multi-site, multi ISA server configuration and I'm puzzled about automatic configuration of proxy settings. Microsquish's documentation does not address my issue.

If you select the "Automatcially detect configuration" checkbox, does the DHCP option 252 setting or the DNS wpad record take priority?

I'd like to have one site to use it's local ISA server by setting the DHCP option in it's scope and have the other site use it's local ISA server by setting it's DHCP option.  I'd also like to have the DNS wpad record set to the main site's ISA servers to serve as a fall back.

Will the clients at the non-main site use the DHCP option first (and its the local ISA server) or use the DNS wpad record (and use the main site's ISA server)?

KingHollis,

They are genuinely sites (different subnets at different locations seperated by routers with their own DHCP servers).  Same domain.

Your answer is EXACTLY what I was looking for. Thanks.

BTW, where did you find this tidbit of information?
Excellent Nevaar!

A great source for any ISA ish is www.isaserver.org. Also, Thomas W. Shinder writes some good books for Syngress.

Thanks and good luck!
