o      Check logs for errors, failed logins, attacks or system failures.
•      Mid-day Citrix load balance checks.
o      Log into Access suite Console and run Discovery.  Highlight each server in turn and ensure that a balanced load of users are accessing the servers across their respective zones.
•      Verify Accessibility from all user sets.
o      Make sure that the users that are in the farm comprise of all user types so that it is fully accessible from all client types and there haven’t been any changes made to the network environment that would affect users.
6.3.2      Weekly Tasks
•      Reboot Servers
o      At a minimum a reboot should be scheduled to maintain general windows operations weekly.  Make sure all Citrix services restart properly.
•      Check fragmentation of each Citrix Server and Web Interface server.
o      Can be scheduled or scattered across a two week span, but the general health and performance of a Citrix server can be greatly affected by the fragmentation of the Citrix and web servers.
o      Defragment the hard drive if you see fragmentation starting to set in.  
•      Check Event Logs for errors.
o      Check application and system logs for possible problems that are occurring inside the farm and look them up to see if they are benign or will become issues.
6.3.3      Monthly Tasks
•      Backup the Datastore.
o      Run a backup of the datastore so that there is a fairly recent copy of the datastore in the event of corruption which will maintain a good collection of changes.
o      Keep at least 3-6 months worth of backups of the datastore (does not take up a lot of space.)
•      Check for Windows Updates and validate with Citrix for compatibility
o      If there are no compatibility issues with what the patch will be affecting and the use of that server then you should keep your servers patched according to your company policy.  
o      Read the patch notes CAREFULLY and apply them to a single server and TEST ACCESS AND ALL PUBLISHED APPLICATIONS prior to rolling it out to the rest of the farm servers.
o      The following link can be used to see known issues with Microsoft security patches and hotfixes: http://support.citrix.com/pages/microsoft/
•      Check for Citrix Hotfixes
o      As the Windows OS is tweaked and patched and improved, there may be patching required to the Citrix architecture to keep it in step with its host server.
o      Read the patch notes CAREFULLY and apply them to a single server and TEST ACCESS AND ALL PUBLISHED APPLICATIONS prior to rolling it out to the rest of the farm servers.
•      Reboot Citrix NetScalers
•      Check for ICA Client Updates
o      Check to see if there are any updates to the ICA Clients that your users access your farm with and verify their benefits to your users prior to planning a client update.  http://www.citrix.com/English/SS/downloads/downloads.asp?dID=2755

o      Open the Access Suite Console and run discovery and verify all servers are still connected and communicating after the change has been made.
•      Verify Connectivity to the Datastore and Licensing.
o      On the affected servers make sure that the server can contact the license server and the Datastore.
•      Test user access to use the new server/application/resource
