Win7, 64 bit, Windows Certificate Services Client-Auto Enrollment

Hi, in the Event Viewer I have been getting an error, Event ID 64. I have followed it up, but when I click on the Certificate to renew it, I get message that Windows cannot renew it. Apparently the Certificate will expire on 2/7. I tried to delete it and I get message that it is needed for encryption. Below is the exact message. Do I have to do anything????

If the system is part of a domain, it could be a problem with either the certificate server(s) in the domain, the domain computer account, permissions on the certificate server, etc. Is this machine joined to a domain?

Hi Guy, thanks for your suggestion, I have followed it all and then Windows informed me that the Certificate cannot be renewed. A template is mentioned, but I have no idea what to do about it. I have meanwhile found that in IE9, under Content, Certificates, the Certificate is listed (the only one). Apparently it was issued in February and expired about a week later. I also found that this is a public key and I also have a private key. When I tried to delete it, the message comes up, that I will no longer be able to Decrypt encrypted messages. Maybe you have further suggestions. Thanks Sewcat7

Hi Cluberti, thanks for your answer. I am not quite sure, what it means to be joined to a domain. It is a standalone PC (home user), although in our house there also is a laptop and a Mac (same ISP). I have meanwhile found the certificate under IE9, Internet Option, Content, Certificates. It is a Token Signing Public Key and it expired on 12/2. The reason for it seems to be Client authentication and I seem to also have a private key. I tried to delete it, but it comes up with the message that encrypted messages can then no longer be decrypted. Sewcat7

A bit beyond me as well. Generally the certificates are updated automatically without user intervention. If there is no impact on your usage, I wouldn't be concerned. Perhaps cluberti in his infinite wisdom will have more info

If it's only in IE that you see it listed, it should be safe to remove in a home user scenario as it would only be used for authentication to a site or to encrypt (SSL) the contents of your communication with a site.

Hi Cuberti, before I delete it, it was also listed in the Registry under Personal Certificates. I will create a Restore Point and see what happens. Thanks for your help. Sewcat7

Yes, it was probably used for authentication to a web site somewhere at some point (given the age, it wasn't recent). Restore point isn't a bad idea, but you should be OK.
