Inheritance flags don't seem to do anything

VB 2005 & .Net 2

I'm trying to add a user group with Full Control applied to "This folder, subfolders, and file" but it seems to keep getting varied results.

The Full Control permission consistently works but it's always applied to "This folder only". Any ideas?

Private Sub AddDirSecurity(ByVal Filename As String, ByVal Account As String, ByVal Rights As FileSystemRights)
    Dim dInfo As New DirectoryInfo(Filename)
    Dim ruleF As FileSystemAccessRule

    ruleF = New FileSystemAccessRule(Account, Rights, InheritanceFlags.ObjectInherit And InheritanceFlags.ContainerInherit, PropagationFlags.None, AccessControlType.Allow)

    Dim dSecurity As DirectorySecurity = dInfo.GetAccessControl
    dSecurity.AddAccessRule(ruleF)

    dInfo.SetAccessControl(dSecurity)

  End Sub

It seems changing AND to + did the trick

ruleF = New FileSystemAccessRule(Account, Rights, InheritanceFlags.ObjectInherit + InheritanceFlags.ContainerInherit, PropagationFlags.None, AccessControlType.Allow)
