I have a scanning target type of Active Directory Computer Path, with the Adsi path as: ou=Domain Controllers,dc=xxx,dc=x,dc=xxxxxxxx,dc=com And it's only picking up two of the 36 domain controllers we have. The operatingSystem attribute of each DC has "Windows Server 2008 R2 Standard" Can you tell me why Lansweeper can't find the rest of these DC's?
