We are currently migrating from Windows NT 4 to Windows XP. For about
one year we will have both operating systems running. Now we want to
assign application objects to Windows NT 4 only and others to Windows XP
only. All applications objects with OS version < do not appear
in Windows XP, but those with OS version >= do all appear in
Windows NT 4.

Do I do something wrong or how can I assign applications explicitly to
Windows XP?

We use ZENworks 6.5 SP2 on the server and the Windows XP client. On the
Windows NT 4 client we use ZENworks 4.

Thanks for your help,
