The instructions provided describe how to direct ArcGIS clients in the Citrix environment to different license manager servers.
For each ArcGIS client, set the license file variable as a User level environment variable. Ensure there are no other conflicting ESRI_LICENSE_FILE, ARCGIS_LICENSE_FILE, or LM_LICENSE_FILE variables set as a System or User environment variable.
Variable: ARCGIS_LICENSE_FILE Value: @license_server_hostname
Variable: ESRI_LICENSE_FILE Value: @license_server_hostname
Note: The license file environment variable takes precedence over the License Manager setting in the Desktop Administrator.
