WAP 2012 R2 Showing Failed Operation Status

Environment:

  • Active Directory Federation Service (AD FS) role configured on Windows 2012 R2 Active Directory Directory Services (AD DS) Domain Controller (DC)
  • WAP 2012 R2 (not domain joined)
  • Office 365 tenant subscription w/ on-premises AD synchronizing a federated domain

 

Error: Under the Remote Access Management console on the WAP Server, Operation Status node shows Web Application Proxy and Web Application Proxy Core as failed while AD FS Proxy status is working. Also, the following error message is observed in the event logs:

Component : Web Application Proxy Core

Cause: Experienced the preceding error after certificate changes in the AD FS farm.

Install-WebApplicationProxy -CertificateThumbprint '<THUMBPRINT OBTAINED FROM PREVIOUS PS COMMAND OUTPUT>' -FederationServiceName 'adfs.contoso.com' (change 'adfs.contoso.com' to your specific STS URL)

Restart-Service adfssrv
