ArcMap says not licensed, but ArcGIS Administrator says licenses are avaliable

[RichardDaniels]

In ArcGIS Desktop 10.3.1 (and now ArcGIS Desktop 10.5.1 after upgrade) I have a computer were ArcMap will not start. When I attempt to start ArcMap (or ArcCatalog, ArcScene, etc.)  it says 'You are not licensed for ArcGIS for Desktop Basic. Use the ArcGIS Administrator to view the software available'. When I run ArcGIS Administrator it shows I've select Basic and that I have many BASIC licenses available. Pinging the license server returns the expected IPv4 results. I've check the IPv4 connection and it is active (vs. IPv6).

Ideas?

When you upgraded your license, did you also upgrade your license manager to License Manager 10.5.1?

[RichardDaniels]

yes the ArcGIS license manager is at 10.5.1.

Note - it is not a user environment issue since multiple people have had the same issue on this machine.

Did you the expiry date also? Could you share a screenshot of the availability list in ArcGIS Administrator?

[RichardDaniels]

As requested. 

I also installed ArcGIS Pro on this machine. I have Pro setup to use Concurrent Use licensing and the licenses area installed on the same server as ArcGIS Desktop licenses. Interestingly ArcGIS Pro can reach the server and get a license (Basic) while ArcMap, on the same machine, cannot.

In this case adding the port number to the license server name 27004@myLicenseServer appeared to fix the issue. We had tried the FLEXLM_TIMOUT=5000000 (5 seconds) but that appeared to have no impact on this issue since the 'you are not licensed' window would pop up immediately after starting ArcMap (no 5 second delay was seen).

I also found that the registry setting for in [HKCM\SOFTWARE\WOW6432Node\ESRI\License10.5] for the "DESKTOP_CONFIG"  key was set to "FALSE". I changed this to TRUE to match my other working installations. How this became FALSE is unknown.

Note - the office location with the problem was using a VPN as well.

Thanks for the ideas :-).
