1. New Fallback Printer Driver.
The new fall back printer driver feature provides the ability map a client printer even if the is not installed on the Terminal Server. Much like the Citrix Universal Print Driver Feature in Presentation Server.
This new feature is configurable with Active Directory Group Policies when the 2003 SP1 is installed.
2. Authentication and Encryption for Terminal Services Connections.
By default Terminal Services Remote Desktop Protocol Client uses Data Encryption, the new feature provided with 2003 SP1 provides Authentication Indentification for each Terminal Server using SSL (TLS) to secure RDP, and SSL (TLS) will run on port 3389.
3. New Group Policy Settings for Terminal Services Licensing.
The new Group Policy setting "Set the Terminal Server licensing mode" determines the type of Terminal Server client access license (CAL) a device or user requires to connect to a Terminal Server.
When this setting is enabled, you can choose one of the following two licensing modes:
Per User: Each user connecting to the terminal server requires a Per User TS CAL.
Per Device: Each device connecting to the terminal server requires a Per Device TS CAL.
4. Update to Group Policy Setting for Starting a Program on Connection to a Terminal Server.
The Group Policy setting "Start a program on connection" configures Terminal Services to run a specified program automatically when a client connects to a terminal server.
If you have single purpose Terminal Servers in a Silo setting, this new feature could work nicely for you. However, I suppose one could create and ADM template with this single setting and create application group policy objects, and apply application groups to apply these policies.
