The maximum length of a computer object (the pre-Windows 2003 samaccountname) in Active Directory
When using vastool join, QAS will truncate the machines hostname to the first 15 characters. This is the NetBIOS limitation (15 + $).
The vastool join command has a
-n option that allows you to specify a different name for the computer object than that which vastool would usually generate from your hostname. The computer name specified with the
-n option should be either the fully qualified DNS name or the NETBIOS name for the computer object.
You can specify the -n option at join time and this will allow a maximum of 19 characters. This is the maximum length allowed in Active Directory (19 + $).
# vastool -u administrator join -n mynewname.yourdomain.com yourdomain.com
