FLEXlm license finder issue

During customization of 3ds Max 2009 Software Package for Network deployment described on AutoDesk web site (http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=14195309&linkID=9241177), Network License Server has been configured:

But after the installation when 3ds Max has been started, from some reason the value for Network License Server previously configured in Network deployment package is not accepted, FLEXlm license finder pop-up and ask for License File or License Server.

Solution for this can be adding System Environment variable ADSKFLEX_LICENSE_FILE with the value of @SERVERNAME and deploying on the workstations using GPO Preferences.

@SERVERNAME - is the name of your Network License server
