Assigning Notes 6 in Active Directory doesn't work

I have problems with assigning Lotus Notes 6.0.1 in Active Directory.

Installation target is a client with Windows XP. Assigning applications in Active Directory is standard software distribution method for my customer and users are supposed to run installation by selecting the application on the Start menu. The problem is that advertised shortcuts are not shown in Start menu, application is only shown in Control Panel, Add/Remove Programs.

Has anyone experience of this problem and how to resolve it?

Thanks,

Pia
