trend micro exchange and ad scan

hi

i use to have symantec on my sbs2000 + dc2000
i trend it with trend micro csm.

i think i made a mistace beacuse the important thing is support which seems to be not so proffisional.

first i need to scan with the Server Security Agent my sbs and my other dc.
so, i need to put the sbs in a group, and the other dc in a group and set
i can configure scan by scheduled, manual and real time.

does someone set this in his invironment?

thanks
