Azure MFA NPS extension not working

Question

Hi,

we have an RDS server with Azure NPS extension, to take on prem server RDP. As checked, the Microsoft NPS certificate is expired on the NPS server, try to update the certificate using the command. "New-AzureMfaTenantCertificate -TenantId 'xxxxx'" but the same issue, what is the best approach to fix them, do we need to re-install the Azure NPS extension, please suggest.

Thanks

Vishnu
