For controlling drive mapping, you may be able to create a Citrix policy
that controls drive mapping and apply/deny it based on the client's IP. 

Software Restriction Policies are incredibly powerful.  Much better than
the "Don't run specified Windows applications" GPO and AppSec.

Malcom

What MS policy settings do you use to catch the 95%??

We would prefer the users to use the Citrix client as they have it
installed and we have had issues with Java versions in the past.

If I created a new ICA connection, can I somehow direct external users
to use that ICA connection (perhaps via AD group membership).  This
would allow me to have a more locked down configuration for external
users and internal users would be unaffected.  Is this possible?

Thanks
