The certification authority service is installed on this computer, problem help

[oldwhs12]

I have purchased a used HP Proliant Microserver Gen 7.  I have installed WHS 2011 on it. I wanted to start with a clean slate and tried to change the Workgroup name.  The machine tells me “The identification of the computer cannot be changed because:  The certification authority service is installed on this computer”.   It tells me the former operating system was Windows Server 2008 R2?

Is there a way to reset the server to the initial factory status where I could start over with WHS 2011?  Am I making a big deal out of nothing?

I am here a way over my head and would appreciate your kind help.

cskenney,

 

thanks for your kind response.  I have a setup with the server mentioned. and three Win 10 workstations.  I will try to make the system functional with the server the way it is.  Microsoft no longer uses the workgroup anyway.  Any comments?
