AX Licenese Server. Users get "unable to aquire license" and AX Admin shows blank license counts
After uninstalling KB4457129 and rebooting the license server started showing licenses again and logins were permitted.
Metasource had sent the following about KB4457143 but it was not installed on the server. KB4457129 also had a MS Kernel update like KB4457143
KB4457143 ApplicationXtender Licensing Issue
MetaSource and OpenText have discovered an issue with the latest September
2018 Microsoft .NET Framework update, KB4457143. After applying this
Microsoft Windows Update to Server 2012 R2 Operating Systems with OpenText
License Server installed, hardware fingerprints generated on the AppXtender
License Server machine change and are then logged as invalid. As a results,
the product license files obtained through My Support and added to License
Server as also invalid.
The exact update is from September 11, 2018—KB4457143 (Security-only
update). According to Microsoft, the update only applies to Windows 8.1 and
Windows Server 2012 R2. Since AX only supports its server components on
server operating systems, Windows Server R2 is the only one affected. This
is happening because the Kernel is being changed which also changes the
fingerprint description of the AX LS server.
OpenText has issued this bulletin as a solution. However,
MetaSource Technical Services have found that, in most cases, if you remove
the update from the server the issues will be resolved. In some case, this
has not resolved the issue and new license requests are still needed.
