Requesting certificates via Network Device Enrollment Service (NDES) fails with HTTP error code 500

Assume the following scenario:

  • A Network Device Enrollment Service (NDES) is implemented in the network.
  • The NDES server uses a domain account for the identity of the SCEP IIS application pool.
  • Requesting certificates via NDES fails with HTTP error code 500 (Internal Server Error).
  • Calling the mscep and mscep_admin pages also fails with HTTP error code 500.
  • Even after an iisreset or restart of the NDES server, no event appears after calling the mscep or mscep_admin page that the NDES service has started or that there were errors.

The Network Device Enrollment Service (NDES) logs the error message "The Network Device Enrollment Service cannot be started (0x80004005). Unspecified error"

Assume the following scenario:

  • An NDES server is configured on the network.
  • When accessing the NDES request web page (mscep) and the NDES administration web page (certsrv/mscep_admin), HTTP error 500 (Internal Server Error) is reported with error code 0x80004005.
  • Events No. 2 and No. 8 are logged in the application event log:

  • The role is installed on a separate server, not on the certification authority directly.
  • A user attempts to request a certificate via Certification Authority Web Enrollment or submit an existing certificate request to the certification authority.
  • The request takes a very long time and finally fails with HTTP code 500 "Internal server error":
There is a problem with the resource you are looking for, and it cannot be displayed.
