ISA Server and DNS Server – What´s the connection?

I´ve seen a lot of threads on web boards regarding ISA firewall issues like:
– ISA is taking forever to display web pages;
– I´m using ISA server and it is not using whole bandwidth;
– My publishing web site is very slow to open;
Well, I usually respond to those threads using a simple formula: ISA + Misconfigured DNS = Slowness.
ISA server requires a well-configured DNS server for it to work.
Yuri Diogenes did it better. He wrote a post at ISA/TMG team blog about ISA connection time out duo a misconfigured DNS and dug into it!
