License Manager Guide: License manager installation and startupLicense Manager Guide: Using the ArcGIS License Server AdministratorHow To: Clear or delete trusted storage for concurrent-use and single-use licenses
Since then, we've cleared the firewall, re-read the license file, created and installed an new license file, uninstalled and reinstalled the license manager software, and modified the license file to set an inbound rule on the range of TCP ports. Rebooted both the manager and the server multiple times. Have not found any service packs for 10.2.2 License Manager.
For what it's worth, I found it easier to change the Integraph license manager and let ArcGIS have first dibs at port 2700. All you need to do is run the Integraph License Administrator and change the port# from the menu. No need to start/stop services and muck around with text files and so on, the app handles it all. 2b1af7f3a8
