in past there 2 ca's live on our network.  now, both shut off , neither of them have valid certificates.  i in process of upgrading dc's 2008r2.  i have first r2 server installed , running, i'm getting 2 application errors in event log every 8hrs.  i have included both of these errors below.  ultimately, want these errors go away cannot find creating them.

any can offer appreciated.

hi,

there must still policy affecting dcs enabling auto-enrolment. other way of stopping enrolment amend permissions on certificate template - domaincontroller in example pasted in original message - domain controllers not have auto-enrol permission on template. can done certificate templates mmc (certtmpl.msc) or enterprise pki in server manager. may need install relevant admin tools see this.
