Event ID 31 — AD CS Online Responder Service

  • Article

Applies To: Windows Server 2008

The status and functioning of the Microsoft Online Responder service has dependencies on numerous features and components, including the ability to access timely certificate revocation data, the validity of the certification authority (CA) certificate and chain, and overall system response and availability.

Start Online Responder service performance counters

To perform this procedure, you must have membership in local Administrators, or you must have been delegated the appropriate authority.

To fix problems that are preventing performance counters from starting:

  1. On the Online Responder, click Start, point to Administrative Tools, and click Reliability and Performance Monitor.
  2. Evaluate system memory and disk usage and, if necessary, add or adjust physical or virtual memory or hard disk space.
  3. Restart the computer.
  4. Click Start, point to Administrative Tools, and click Services.
  5. Click Online Responder Service, and click Restart.
  6. If the error persists, contact Microsoft Customer Service and Support.

Verify

An Online Responder serves as an intermediary between clients that need to check certificate validity and a certification authority (CA) that issues certificates and certificate revocation lists (CRLs). To verify that the Online Responder service is functioning properly, you need to isolate the Online Responder and client from the CA and any CRL distribution points to confirm that revocation checking continues to take place and that revocation data is originating only from the Online Responder. The best way to confirm this scenario is to complete the following steps that involve the CA, the client, CRL distribution points, and the Online Responder:

  • Issue new certificates.
  • Revoke a certificate.
  • Publish a CRL.
  • Remove CRL distribution point extensions from the issuing CA.
  • Confirm that client computers can still obtain revocation data.

To perform these procedures, you must be a member of local Administrators on the computer hosting the Online Responder and on the client computer, and you must have Manage CA permissions on the computer hosting the CA, or you must have been delegated the appropriate authority.

Issue new certificates

To issue new certificates:

  1. On the computer hosting the CA, click Start, point to Administrative Tools, and then click Certification Authority.

  2. Configure several certificate templates to autoenroll certificates for a computer running Windows Vista or Windows XP Professional.

  3. When information about the new certificates has been published to Active Directory domain controllers, open a command prompt window on the client computer and enter the following command to start certificate autoenrollment: certutil -pulse.

    Note: It can take up to eight hours for information about new certificates to be replicated to Active Directory domain controllers.

  4. On the client computer, use the Certificates snap-in to confirm that the certificates have been issued to the user and to the computer, as appropriate. If they have not been issued, repeat step 2. You can also stop and restart the client computer to initiate certificate autoenrollment.

Revoke a certificate

To revoke a certificate:

  1. On the computer hosting the CA, click Start, point to Administrative Tools, and then click Certification Authority.
  2. In the console tree, click Issued Certificates, and then select the certificate you want to revoke.
  3. On the Action menu, point to All Tasks, and then click Revoke Certificate.
  4. Select the reason for revoking the certificate, and click Yes.

Publish a CRL

To publish a CRL:

  1. On the computer hosting the CA, clickStart, point to Administrative Tools, and then click Certification Authority.
  2. In the console tree, click Revoked Certificates.
  3. On the Action menu, point to All Tasks, and then click Publish.

Remove all CRL distribution point extensions from the issuing CA

To remove all CRL distribution point extensions from the issuing CA:

  1. On the computer hosting the CA, click Start, point to Administrative Tools, and then click Certification Authority.
  2. Select the CA.
  3. On the Action menu, click Properties.
  4. On the Extensions tab, confirm that Select extension is set to CRL Distribution Point (CDP).
  5. Click any CRL distribution points that are listed, click Remove, and click OK.
  6. Stop and restart the CA.
  7. Configure a new certificate template, and complete autoenrollment again.

Confirm that client computers can obtain revocation data

To confirm that client computers can obtain revocation data:

  1. Click Start, type mmc, and then press ENTER.

  2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.

  3. On the File menu, click Add/Remove Snap-in, click Certificates, and then click Add.

  4. Select the user or computer account to whom the certificate was issued, click Finish, and then click OK.

  5. Open the Personal Certificates store, right-click the most recently issued certificate, point to All Tasks, and then click Export to start the Certificate Export Wizard. Export the certificate to a .cer* *file.

  6. Open a command prompt window.

  7. Type **certutil -url<exportedcert.cer> **and press ENTER.

    Exportedcert.cer is the file name of the certificate that was exported in the previous step.

  8. In the Verify and Retrieve dialog box that appears, click From CDP and From OCSP, and confirm that the revocation data is retrieved from the Online Responder and not from a CRL distribution point.
