Charles,

I don't understand. As you said I don't have a fixed IP address for my
sever. But in step 7 you say to enter the IP address. What IP should I
enter? The range of possibles that I might have?

If I add the domain name from SBS1, is it going to try to DNS verify that
name against the address that is logging in?

Thanks,
Bernie
