SYMPTOMS

When you try to enroll for a certificate against an enterprise certification authority (CA), you may receive one of the following error messages:

Web enrollment:
Certificate Request Denied

Your certificate request was denied.

Contact your administrator for further information.

Certificate Request Wizard:
The certification authority denied your request. Unspecified error.

CAUSE

This behavior may occur if the certificate enrollment request is using a recently-created certificate template. When a new template is added to the CA, the HKEY_CURRENT_USER cache is immediately updated but the HKEY_LOCAL_MACHINE cache is not immediately updated. The HKEY_LOCAL_ MACHINE cache is updated in the next 15 minutes if the CA or the domain controller are on the same computer, and in the next 10 minutes if the CA or the domain controller are in a distributed configuration.

RESOLUTION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this behavior, if you cannot wait for the applicable length of time, you can manually update the certificate template cache. The cache for computer certificates is in HKEY_LOCAL_MACHINE and the cache for user certificates is in HKEY_CURRENT_USER.
  • To force the cache update for a user certificate request, delete the following registry value from the client:
    HKEY_CURRENT_USER\Software\Microsoft\Cryptography\CertificateTemplateCache\Timestamp
To force the cache update for a computer certificate request:
  1. Delete the following registry value from the client:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\CertificateTemplateCache\Timestamp
  2. Delete the following registry value from the CA:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\CertificateTemplateCache\Timestamp
  3. Restart the Certificate Services on the CA.
