hc on dns serv

hi all,
 
ive installed HC8 on a windows web 2008, this will act as my master server.
 
my question is..... my dns server is on a seperate box (ubuntu). does that mean i have to install HCLinix on this box? i'd rather not have anything else installed on this box.
 
if i do have to install another copy of HC on this box does that also mean i have to install a copy of HC my database box, mail server box etc etc
 
thanks
 
 

i got in contact with sales directly. the answer is yes in case anyone reads this in the future
