I have terminal services 2003 and citrix presentation server 4.0 setup. If I logon as a user who is a admin on the server the local drives map through fine. If I logon as a user who is not and Admin the local drives will not map through. I have checked in both the ICA client settings and RDP settings and both are set to allow local drive mapping. Is there any security setting I need to change to allow all users to map their local drives.
