Hi
I am trying to promote a customers stand-alone server from a workgroup to a new domains domain controller but I found out that someone has already installed the Certificate Server on the server.
Now I can´t promote the server to a domain controller as I get an error message during the Prerequisites Check......
"Verification of prerequisites for Domain Controller promotion failed. Certificate Server is Installed"
I have been trying to find some type of workoround for this but I am not able to find any, all I has been told is that the you have to uninstall the AD CS before I can promote the server to a domain controller.
When trying to remove the AD CS role I get this error:
"The status of the role services on the target machine cannot be determinated. Please retry. The error is Connecting to remote server SERVER2017.local failed with the following error message: The WinRM client cannot process the request. If the autenthication scheme is different from Kerberos, or if the client computer is not joined to a domain, then HTTPS transport must be used or the destination machine must be added to the TrustedHost configuration settings. Use winrm.cmd to configure TrustedHosts. Note that computers in the TrustedHosts list might not be authenticated. You can get more information about that by running the following command: winrm help config. Fore more information, see the about_Remote_Troubleshooting Help topic.."
Can someone out there help me with this..... I am really stuck here...
