Did you solve the certificate validation error?

Question

A certificate validation operation took 15019.0726 milliseconds and has exceeded the execution time threshold.

Answer 1

I solve this in couple of my farms. option 2 and 3 i used.

• In the Local Group Policy Editor, we changed the Certificate Path Validation Settings to disallow automatic updating of certificates, but this did not help. [ Computer Configuration > Windows > Security Settings > Public Key Policies > Certificate Path Validation Settings]
• In the Hosts file, we added an entry for crl.microsoft.com to point to the localhost, 127.0.0.1. That also didn’t seem to have any effect on the problem, as we continued to see those errors.

• We then installed SharePoint root certificate on all the SharePoint servers, in the Certificate Root Authority Store. We exported the out-of-the-box SharePoint certificate using PowerShell, and then manually installed on each server. After that we rebooted all the servers, and observed the problem reoccurrence –however no further issues were seen in the event logs anymore. The following PowerShell commands were used:

  $rootCertSP = (Get-SPCertificateAuthority).RootCertificate
  $rootCertSP.Export(“Cer”) | Set-Content C:\rootCertSP.cer –Encoding Byte

open mmc Add snap-in Certificates, Computer account, Local Computer, OK In Trusted Root Certification Authority, Certificates, Import certificate export.
