Event ID 105 — AD CS Certification Authority Certificate and Chain Validation

  • Article

Applies To: Windows Server 2008

Chain or path validation is the process by which end-entity (user or computer) certificates and all certification authority (CA) certificates are processed hierarchically until the certificate chain terminates at a trusted, self-signed certificate. Typically, this is a root CA certificate. Active Directory Certificate Services (AD CS) startup can fail if there are problems with availability, validity, and chain validation for the CA certificate.

Resolve

AD CS deleted an invalid certificate in Active Directory Domain Services

Active Directory Certificate Services (AD CS) deleted an invalid certificate from Active Directory Domain Services (AD DS). The certificate that was deleted is specified in the event log description.

AD CS will delete a certificate if it determines that certificates in the AIA container in AD DS are not consistent with the certificates in the local store of the certification authority (CA).

Verify

To perform this procedure, you must have Manage CA permission, or you must have been delegated the appropriate authority.

To confirm that the certification authority (CA) certificate and chain are valid:

  1. On the computer hosting the CA, 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. Click Computer account, and click Next.
  5. Click Finish, and then click OK.
  6. In the console tree, click Certificates (Local Computer), and then click Personal.
  7. Confirm that a CA certificate that has not expired exists in this store.
  8. Right-click this certificate and select Export to launch the Certificate Export Wizard.
  9. Export the certificate to a file named Cert.cer.
  10. Type Start, cmd and press ENTER.
  11. Type certutil -urlfetch -verify <cert.cer> and press ENTER.
  12. If no validation, chain building, or revocation checking errors are reported, the chain is valid.
