CRL distribution is the core component of the certificate revocation check.so the latter two options are indirectly and totally dependent on the CRL. The CRL configuration has components: Base CRL - This will contain the whole complete list of revoked certificates (non-expired). So whatever the revoked certificates we have will be present here. It does not check for revocation. Either the OCSP server is provided by the certificate issuer itself which already has the list of revoked certificates (since the issuer revoked these itself) or in case of OCSP stapling the web server gets the (signed) OCSP response from the issuer and includes it unchanged inside the TLS handshake. Get Certificate Revocation List information by certificate information. Oh, and you might want to simply check the computer date and time - a common reason for certificate issues.steve Microsoft MVP Windows Live Windows Live. Answered 5 Replies.

Introduction Certificate revocation is the process of removing the validity of a certificate before the certificate is set to expire. For example, an employee is issued a certificate for smart card logon with a certificate expiration of 1 year. If that employee leaves the organization 5 months later, the certificate should be revoked to prevent its use. When a certificate manager revokes a certificate, the certificate manager can specify the reason for revoking the certificate.
When a certificate is revoked, a reason must be provided to justify the revocation of the certificate. This revocation reason serves as a useful tracking mechanism for why certificates are revoked in an organization. For example, when reviewing the reasons why certificates are revoked over a one-year period, an organization might realize that a high number of certificates were revoked because of a key compromise. This might prompt an organization to evaluate their security practices to reduce the number of key compromises.
Reason codes When revoking certificates, use one of the following reason codes:
■ KeyCompromise. The private key that is associated with the certificate is compromised and is in the possession of an unauthorized individual—for example, if a portable computer is stolen or a smart card is lost.
■ CACompromise. The smart card or disk on which the CA's private key is stored is compromised and is in the possession of an unauthorized individual. When a certificate manager revokes a CA's certificate, all certificates issued by that CA are considered revoked.
■ AffiliationChanged. An individual is terminated or has resigned from an organization. It is not necessary to revoke a certificate when an individual changes departments unless your security policy requires that each departmental CA should issue certificates to the individuals in that department.
■ Superseded. A new certificate must be issued if a smart card fails or the legal name of a user has changed. The new certificate supersedes the previous certificate, which must be revoked.
■ CessationOfOperation. If your organization decommissions a CA, use this revocation code to revoke the CA's certificate. Do not revoke the certificate if the CA publishes CRLs for the currently issued certificates but does not issue new certificates.
■ CertificateHold. A temporary revocation that indicates that a CA will not vouch for a certificate at a specific time. After a certificate is revoked by using CertificateHold, you can later unrevoke the certificate.
Note To unrevoke a certificate revoked with CertificateHold, type certutil -revoke certificateserialnumber unrevoke. The certificate serial number can be found in the details pane of the certificate.
■ RemoveFromCRL. If you revoke a certificate by using CertificateHold, you can unrevoke the certificate. The unrevoking process still lists the certificate in the CRL, but with the revocation code set to RemoveFromCRL. The RemoveFromCRL reason code is specific to the CertificateHold reason and is only used in delta CRLs.
■ Unspecified. You can revoke a certificate without providing a specific revocation code. Using Unspecified is not recommended, however, because it does not provide an audit trail that identifies why a certificate was revoked.

Abstract: If you check your Skype for Business frontend server event log you see multiple warnings for the Windows Fabric related to the cert chain trust and the certificate revocation list (CRL).
The errors in the event log show up similar like the following:
As 0x1000040 implies:
#define CERT_TRUST_REVOCATION_STATUS_UNKNOWN 0x00000040
#define CERT_TRUST_IS_OFFLINE_REVOCATION
The first line above is nearly the same as the 2nd line. This lead to the following solution:
Solution:
The error show up if the CRL, which is specified in the SSL certificates you are using on your Skype for Business (=SfB) environment, couldn´t be reachable from your SfB frontend server. This could be due to a firewall issue (e.g. needed port isn´t open) or a proxy exclusion list isn´t set via 'netsh winhttp set proxy'. Once the server can reach the CRL again the problem should be solved.
Update Certificate Revocation List
To find the CRL you could open the SSL certificate and check the 'CRL Distribution Point' property for more details.
Keep noted that most Skype for business (aka Lync) server use a certificate from an internal Microsoft certificate autority (MS CA). So do not check only the external CRL for the public certificate you are using, check also the internal CRL!
