Windows Server 2012 R2 Certificate Authority

I have numerous devices on my internal network that operate with self signed certificates.  Those devices include firewalls, switches, laser printers just to name a few.  We run a vulnerability scanner and it's complaining that the certs aren't issues from a trusted authority.  I found that I can't buy certs from an outside party since I would be applying to devices on a private address range.  I installed Certificate Services on my Server 2012 R2 domain controller and am having issues generating certificates.  I'm trying to apply a certificate to one of the admin interfaces on one of my hp laserjet printers.  What kind of cert should I try to request for this?  I assumed it would be a web server cert but I keep getting error messages like this below.

Request Mode:
newreq - New Request
Disposition:
(never set)
Disposition message:
(none)
Result:
No mapping between account names and security IDs was done. 0x80070534 (WIN32: 1332 ERROR_NONE_MAPPED)
COM Error Info:

LastStatus:

Can you give a little more information? Have you installed the certificate on the printer, or just initiated a request? Where do you see this message? A web server certificate would be used on the HTTPS admin interface for a printer, so you are using the correct type of certificate. However, the meaning of the message your getting needs some context.

I navigated to servername/certsrv and selected request a certificate, selected create and submit a request to this CA, select web server as the template and select create new key set, fill in the necessary information such as name, company, ou, etc.  Request format is CMC and hash algorthim is MD5.  I then receive the following error

Error  


Your request failed. An error occurred while the server was processing your request.

Contact your administrator for further assistance.

Okay. Go into IIS and make sure the virtual directories are configured to use NTLM authentication. You get that error if you try to perform certificate operations as an anonymous user.

Please explain, why would you care about that scanner's recommendation even? The devices like a laser printer's web server config page don't need external certificates. Who uses them? You, the admin, no one external... so definitely, the vulnerability scanner has driven you into something unneeded.

Adam, thanks for the help NTLM was the fix. McKnife I couldn't agree more with you, I really don't need to satisfy these vulnerabilities but I need to present a report of our vulnerabilities to our board of directors and it would be easier to remediate the vulnerabilities then try to explain certificates.
