Hi, For the last 6months we've been getting our laptops to request a Computer Certificate using a GPO and they have been working fine. Now, for some reason any new laptops will send their request for a certificate but doesn't recieve a certificate back. Have a look on the server and the certificate is sat there in Pending and labelled as 'Taken Under Sumission'. No configuration has been changed to either the GPO or CA, its just stopped working. I've checked, re-checked and rebooted but it just won't automaticly give out the certificates. HELP, PLEASE! Dan.
