Our website provider accidently revoked a certificate. They have resolved it but some machines are still showing the error while others are fine. I know I can uncheck the security setting for cert revocation checking but I want it to remain on. On a 2012 server running IE11 is there any way to force the update so it picked up the changes. I have already tried clearing the cache rebooting and resetting all IE11 settings but it still shows the same error. If I uncheck the revocation setting it obviously works fine. thanks.
