The ArcGIS license server has been updated and the original license server is now working again. The temp license server will probably be shut down at the end of August. Please update your license manager back to the original server.
In order to update your license manager, you will need to open the ArcGIS Administrator. Make sure you have the “Advanced concurrent use” product selected and define the license manager as oit202lic.oit.ncsu.edu (please make sure there are no spaces if you copy and paste it). Select OK once you have both of those done and you should be good to go.
We are sorry for any inconvenience over the past month you have had.
