IT Challenge
IT is under intense pressure to simplify the management of enterprise resources and make them more cost-effective to operate
IT organizations are coping with these technical, economic and business challenges through consolidation
We found Citrix to be an easy way to provide a single point of access to theon-demand enterprise from any location, for any number of people, using many devices, over any connection.
Benefits of the Citrix DeploymentBenefits for IT
– Centrally consolidate applications, reducing costs and complexity
– Increased productivity– Resilience to business/technical disruptions– An “observation dashboard” – where, how, when and
by whom systems are accessed– Software as a utility– More Control
Benefits for Users– Just like the office – no compromise in experience,
regardless of location – Always on, always there – just connect & compute,
over any network– Dynamically follows you – any screen, any shape,
with many devices

Florida DOT Trns*port Specifics
Florida DOT Trns*port Specifics
• Six Metaframe Servers in Production Farm
• Single Location for Terminal Service Profile Paths
• Single Location for User Application Data
• Batch Files Used to Start Applications
Trns*port General Issues
•DPS Status Monitor.– Port Usable by Only One Person.
•SiteManager Local Database.– Different Database for each – User the same across all servers in the Farm.
•SitePad.– Allow users to sync locally with SiteManager
running on Metaframe server.
Settings to Be Cautious About
• Idle Time Outs
• Limiting Programs to Single Instances
Helpful Changes to Trns*port Suite
• User Settings in KEY_CURRENT_USER Registry Hive
• INI Files Migrated to Window’s Directory
• Dynamic Ports for DPS Status Monitor
