certutil reporting a Cert Authority that no longer exists

We recently put up a 2012 server and using it as a certificate authority. It has been online for a couple of months, however when running certutil, it reports a FQDN server that I fear was set up by an admin that is no longer with the institution. It is not listed in the domain computer/server and does not respond to ping or nslookup. When I run certutil on a client, I get the following report:

Entry 0:

  Sanitized Short Name:         `<X> Root CA'
  Flags:                        `1'
  Web Enrollment Servers:       `'
CertUtil: -dump command completed successfully.

I'm unsure of how to proceed. Need to remove the broadcast and change it to the new cert auth we set up. Suggestions? Thanks in advance. -Brian
