  • Can you download the CRL and check the Effective date and Next update dates and verify that your CRL is up to date. CRL validation will fail if you have an expired CRL. – Tim Liston Mar 05 '19 at 15:33
  • Done. I've verified effective date and next update and it's ok. I also tested the revocation check from a joined domain PC and verification is ok. server which is NOK is a windows 2019 server in a DMZ not domain joined (AD 2008 R2). – Alex Lum Mar 05 '19 at 15:40
  • And you verified that the DMZ server has access to the revocation list? I know you said you could telnet to it, but wasn't sure if that was from the DMZ server or a different client. Powershell: `Invoke-WebRequest 'http://URL/RevocationList.crl'` – Tim Liston Mar 05 '19 at 15:47
  • Yes it have access. I downloaded CRL from it. invoke-webrequest returns status code 200. – Alex Lum Mar 05 '19 at 15:59
  • On windows client domain joined, the certutil command can reach delta. tested from my NOK server from IE and powershell and no problem to reach the delta. Output from PC OK `CRL 0592: Issuer: CN=get-SRV-DC-CA, DC=domain, DC=com a4 67 25 45 41 a8 42 b5 e0 81 9f e0 2e 61 39 5b ae b2 b4 e9 Delta CRL 0598: Issuer: CN=get-SRV-DC-CA, DC=domain, DC=com...........` – Alex Lum Mar 05 '19 at 16:35

The problem is with Delta CRL http url, it points to Base CRL file. Both, Base and Delta CRLs have the same URL, thus, they point to the same file, while these are separate physical files.

  1. Open CA management console (certsrv.msc), select CA properties, switch to Extensions tab. Make sure if HTTP url for CDP ends with <DeltaCrlAllowed>.crl. If not, edit URL (copy existing, delete and add new URL with the same settings) by inserting <DeltaCRLAllowed> variable right before file extension.

  2. open CertEnroll folder and ensure if there are two crl files. One of them includes + character in file name.

if there are two files, make sure if the CRL (with plus sign in file name) is valid.

  1. If http CRLs are hosted on IIS, make sure if double-escaping is enabled on IIS.

when all mentioned issues are fixed, re-publish CRL and try certutil again.
