Cisco VPN Error #42, 43 and 44 -
"Certificate is not valid, or not an online enrollment request." and "Certificate enrollment failed, or was not approved."

Explanation: This error code means that there is a problem with the certificate used.. Again, users shouldn't see this error unless someone is playing with theregistry.. or your Active Directory Windows Admins are playing with/pushing certificates to your PC or there is a problem with the CA (certificate authority, which is usually run by those windows admins who also do AD).. but it is very odd to get a certificate error with your VPN client. If so, it's not usually cused by the end user.. Check with the windows admins to see if anybody was doing anything with certificates
