Contact with the farm data store has been lost. This may indicate server or network problems.


Citrix Presentation Server uses a data store to centralize configuration information for a server farm in one location. The data store is a database that maintains information about the servers, applications, and Citrix administrators in the server farm. Data store connections can be direct, using ODBC, or indirect, using the Citrix IMA service.

Contact with the data store can be lost if the server hosting the data store fails or is disconnected from the network, or if there are problems with the database, ODBC, or the Citrix IMA service.


Check the server hosting the data store and your network infrastructure to determine if there are problems.

If the data store has been damaged, see the Advanced Concepts Guide for Citrix Presentation Server for information about restoring from backup to a new database server.
