Unable to find CA Certificates for Job server

Hi Experts,

I am facing an issue with Job Server. When I try to resync/edit/delete the job server it's showing the following error "

"Unable to find CA certificates for job server. Make sure the CA certificates for job server certificate exist in the LINK_DIR/ssl/trust_certs folder. (BODI - 320050)"

I have tried  by deleting the old entries of 'AL_MACHINE' and re-registering the repository. But still getting the same error.

It's a fresh installation of DS 4.2.1 in server 2008 and the job sever is not active in the designer because of the above issue.

Any solutions please!!!

Thanks in advance,

Abhi
