Request through http, but I cannot get a Computer certificate

Hello,

From a client I type in my browser: http://dc1/certsrv.

Then I get to a screen where I can choose among these certificates: User, Basic EFS, Administrator....and a few more ; but I don't see "Computer certificate" in that list.

Does anyone know how could I get a Computer certificate from that web site ?.

As far as I know, one can add entries to that list, but not sure how to do it.

Thanks in advance!
