This is a completely new area for me. We are getting "13801: IKE Auth Credentials are unacceptable" messages when connecting to our VPN service on a small Windows 2008R2 domain. Doing a google search has lead me to investigate the Certificate Authority. I've looked in the Certificate Authority | Issued Certificates And the one for the VPN Reconnect is marked as expired since a couple of hours a ago. Can some one tell me what the step I need to take to regen/reissue a simillar cert please? FYI:The client certs are not expiring for a number of years so they are fine.
