 SCEP server is not functioning properly or cannot be reached.


 SCEP server requires 2 certificates to be present on the server running NDES services.

  • CEP Encryption Certificate
  • Exchange Enrollment Agent

If any of those certificates expires, NDES services will not be able to run.

To renew CEP certificate do the following:

  • Open MMC console and add certificates snap-in
  • Browse to the CEP certificate located in Personal certificates container
  • Right click and select All Task -> Advanced -> Renew
  • Follow the workflow using the CEP encryption template

Due to Microsoft specification, Exchange Enrollment Agent certificate cannot be renewed using this procedure.

To renew Exchange Enrollment Agent certificate, follow Microsoft KB article 2712186.

Restart IIS or restart the server.

You should now be able to access SCEP server using the following link:
