Question

Error installing scvmm 2022 "Virtual Machine Manager cannot process the request because an error occurred while authenticating 'computer name'"

I checked SPN. The local machine and user accounts are on the same domain. I removed system from domain and re-added.

Hi,

It sounds like you’re encountering a tricky issue with SCVMM 2022. Here are a few steps you can try to resolve the authentication error:

1. Check WinRM Configuration: Ensure that Windows Remote Management (WinRM) is properly configured and running on the server. You can do this by running the following command in an elevated Command Prompt or PowerShell:

      winrm quickconfig
   

2. Service Principal Name (SPN) Configuration: Double-check the SPN settings for the SCVMM service account. Ensure that the SPNs are correctly registered in Active Directory. You can use the setspn command to verify and register SPNs:

      setspn 
   

3. Kerberos Authentication: Make sure that Kerberos authentication is functioning correctly in your environment. Sometimes, issues with Kerberos can cause authentication problems with SCVMM. You can use the klist command to check for valid Kerberos tickets:

      klist
   

4. Firewall and Antivirus: Temporarily disable any firewall or antivirus software that might be interfering with the installation process. Ensure that the necessary ports for SCVMM and WinRM are open.
5. Event Logs: Check the event logs on both the SCVMM server and the target machine for any related errors. Look for errors related to WinRM, Kerberos, or SCVMM.

If these steps don’t resolve the issue, please let me know, and we can explore further troubleshooting options. Good luck!
