An unknown certificate on my IIS server.

Hello,

I am looking at a Windows 2012 IIS server and I see a certificate WMSvc-myiisserver that has an expiration date of 1/20/2015 and it is using SHA1.

I do not recall I ever deploy that certificate on the server.

Would someone advise if that cert is always there by default?  Where do I go to see the vendor of that certificate?

Please see the attached.  

Thanks.

Hi,

It is by default installed with IIS but it is not used. Normally it will use different certificate, self-signed,... but this certificate is not used.

What roles do you have in this server?

Cheers

I am an admin.  I have been trying to find a KB that talks about this and show it to a manager but I am not able to find it.  

Is it okay if I remove it?

That's a self-signed certificate. If you go to the General tab and look at the "Issued by" line, it will show the local server name.  It is an internally-generated certificate for the website management services.

The cert is on sha1.  How can that be upgraded to sha2?

What is this self-signed for?

As I said above, this certificate is intended only for the IIS website management services.  It's internal only and is designed to allow for remote users to manage the web services.  The certificate is created automatically when you install the Web Management Services for IIS.  I don't know of any way to change the hash to SHA256.  I have read some methods for creating SHA256 certificates in Windows IIS, but not for this purpose, since this cert is created automatically.
