Issue: After installing the Windows Client and rebooting, the client reports Endpoint not found error and it is not possible to log in.
Reason: An endpoint for the client exists on the server or in the configuration file of the client.
Workaround:
Remove the endpoint for the client on the server in the Endpoints section of the Administration portal (if the client exists).
Boot in the Safe mode and remove the endpoint_id, endpoint_name, and the endpoint_secret parameters from C:\ProgramData\NetIQ\Windows Client\config.properties.
Reboot the Windows operating system.
