Tom Shinder After reading your article INSTALLING ISA SERVER ON A DOMAIN CONTROLLER. And reading your book, ISA SERVER 2000 my question is it sounds like its almost better for my to reinstall W2K and ISA over again to make DNS server quit having problems. Is that true? I have a multi homed system and I need to reinstall the full version of ISA because I?m just using the 120 day trial version. I have W2K server and I need to purchase ISA. Would I be better off purchasing SBS instead? Ken Schild
