No problem! Are you discovering these machines using IP Discovery or by just looking in the Network Browser (or discovering by domain)?
If you\'re doing it purely by domain (not IP), then the problem is likely due your local machine\'s Master Browser not matching up with the Active Directory. You could try turning on \"Include Active Directory\" in Preferences and see if that helps. It will take longer to discover, but it may be more complete. With this option, machines are cross-referenced between the Master Browser and AD, so machines that are in the AD but not in the Master Browser will show up as \"Computer Offline?\". Try scanning those and see if that works.
Also, this option can also help with domain cleanup of old computers/accounts by showing you this difference.
