gpo in W2K3 Active Directory domain

[PLR]

Dear all,

 

i have an organization unit with user and machine accounts managed by many gpo's.

A subset of the machine accounts are members of a group.

 

I want to set user settings (in fact, User configuration / Windows settings / Internet Explorer maintenance / Connection / Automatic browser configuration) only to the users connected to the machines members of the machines group.

 

I do not want side-effect on machines non-members of the group and others user/machine accounts outside this ou.

 

Any idea with security filtering, loopback processing... ? others ?

 

many thanks for help.

Rgds
