Active Directory Enterprise CA
In many cases I work with clients that use their own Certification Authority to issue certificates for their services, like Microsoft Exchange, Microsft Lync, IIS websites etc. In order for me to issue a certificate I obviously have to know where I can find the CA server... I use the following command: certutil -config - -ping in order to find the CA. If there is a CA with in your network a popup box will appear asking which CA to ping. You then should be able to get the server name from the output that follows on the command prompt.
