Its tough enough managing an enterprise environment today without the added presure of managing seperate management interfaces.
Currently we (Microsoft) have no natural feature rich ADM files that you can sling into Active Directory and set attribute changes to the client registry.
There are a few ADM files out there on Internet. The below is an example of these ADM files.
The ADM files leave tatoo but to get a solid grip and consistent softgrid client environment the ADMs are core!
Now if you need to expand this ADM file to add additional settings or create your own settings you can use Desktop Standards Policy Maker http://www.desktopstandard.com/PolicyMakerStandard.aspx
I have had to do the recently when increasing the softgrid client time out value! Great couple of tools and can really help you manage and simply your client deployments.
