Hi David,

In case it wasn't apparent, that's an environment variable on the web server itself, where the script is running. A site administrator can check if it's set in a way that LabKey Server can see it by going to Admin->Site->Admin Console->Environment Variables. This can be a quick way to check if it's set at all. Someone would need to configure it directly on the web server and then restart Tomcat to get it to pick up the change.

Thanks,
Josh
