Thanks for your reply. We have only one server (which is a DC) running Active Directory Certificate Services. On the machines server manager the ‘Enterprise PIK\CA name’ node it has the following in the list view.<br />

My understanding is that this is read off the AD and this should mean that I am good now through to 2020. Is that correct? Any other suggestions?<br />
<br />
Thanks

that's how it looks to me - best bet though is to look at the certificate chain for any issued certificate; that is a one-stop-shop to check the validity and expiry of the leaf cert, intermediate, and root.

I noticed when installing a new SSL certificate on one of my servers yesterday that my Domain Root Authority certification was expiring next month. When I looked into how to renew it, I noticed that the server that issued it has been delete from the domain by one of my old IT staff. <br />
<br />
I do have an new server running the Active Directory Certificate Service however the certificate does not show therefore I cannot renew it.<br />
<br />
Can somebody assist with some instructions on what the the best way forward is.<br />
<br />
Thanks

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.
