Problem

Consider the following situation:

• RES ONE Workspace 2016 or higher is installed
• Citrix Xenapp is in use in combination with Citrix Machine Creation Services
• Testing the database connection with ODBC result of the test is: Test Completed Successfully
• A direct datastore connection is configured on the Ivanti Workspace Control Agent

After the machine is booted and created with Citrix Machine Creation Services the cache is updated once at boot. After boot the cache cannot be updated. Force cache update does not succeed.

Cause

Test the connection with Ivanti Workspace Control connection with "%RESPFDIR%\svc\res.exe /config" will result in "Connection failed (Connection could not be established:)

Solution

Install the SQL native client in the Citrix Machine Creation Services image.
