You may get a response to this from someone who knows more about it than I
do, but I don't know of any reason why the dns2go service would effect your
internal DNS settings. It seems to me that your DNS would be servicing only
local or outbound DNS requests, while dns2go deals with inbound requests.

If you set it up and it doesn't work, I'd post another question with a
subject relating to dns2go before experimenting with settings - a lot of
people in the SBS groups use that or similar services, so you should be able
to get a specific answer pretty easily.

As you probably know, there are security risks associated with hosting a web
site on your SBS, and it's not considered a "best practice" to say the
least. I hope you'll do a lot of reading about ISA, IIS, and other web site
security topics before hosting a publicly available web site.
