Is anyone familiar with the FlexNET event codes found in the licensing event log? I'm having trouble opening any desktop products and found the following event code: 2000001d. On other machines, there are multiple codes logged, but this is the only one I see. ArcGIS Administrator eventually finds my single use license if I leave it open for awhile. I've gone through full uninstalls / reinstalls which will fix things for a short time, but soon enough the application hangs on initializing license. I'm sure this is an issue for tech support, but was curious is there is a key for event log codes and messages.
