Not sure what you mean by "log-in DNS".

You can import all your computers into Altiris using [Settings > Notification Server > Microsoft Active Directory Import >] Active Directory Import.

Then configure the Symantec Management Agent [Settings > Agents/Plug-ins > Symantec Management Agent > Settings > Agent Install >] Scheduled Push to Computers.
 

If you're looking for Active Directory OU information, you have to enable the AD Import for computers on the SMP.  If you've already done so, you can go to Manage > Organizational Views and Groups and the data you are looking for will be under Active Directory Domains.  It's in the Inv_OU_Membership table in the database.
