Instructions provided describe how to configure Windows 7 Internet Connection Firewall (ICF) to work with the License Manager.
Ports are sometimes blocked for security. Instructions provided below describe the steps to reopen the correct ports and allow ArcGIS to communicate with the License Manager.
An alternative to this procedure is to disable the ICF completely. Consult IT personnel before disabling the ICF.
For systems running ArcGIS and Windows 7 with ICF enabled, including the License Manager server, these steps must be run while logged in to the computer with 'administrative' rights. If the user account does not have administrative rights, contact a system administrator.
By default, the lmgrd daemon starts on port 27000 if the port is available, or else it will start on the next open port within the range 27000–27009.
DO NOT use "PORT=1234" on line two, use one of the following port numbers: 27000-27009.
