ISATAP nslookup command Error

Hi All,

I am referring TLG for configuring UAG DirecAccess. In TLG - Demonstrate Forefront UAG 2010 SP1 RC DirectAccess. In Step 2 Section D ISATAP configuration is given. After following the guide Step By Step in the End when I check the ISATAP with "nslookup isatap" I got an error "localhost can't find isatap: Non-existant domain"



Can anyone help please? 



Thanks
