For Online - Data retrieval failures occurred on a Windows Server 2022 target in Server Manager, the most relevant checks are WinRM connectivity, authentication/SPN issues, alternate credentials, and event log access.
- Check whether alternate credentials are required
In Server Manager, right-click the affected server in the Servers tile and select Manage As.
Use an account that has rights on the target server. This is especially relevant when Server Manager shows manageability errors such as:
- Kerberos target resolution error
- Kerberos authentication error
- Online - Access denied
- Check for WinRM listener/configuration problems on the target server
On the affected server, run these commands in an elevated prompt:
This restores the WinRM listener configuration and performs the default WinRM service/listener configuration.winrm invoke Restore winrm/Config winrm quickconfig - Check for WinRM proxy configuration
Server Manager and related management tools rely heavily on WinRM. A WinHTTP proxy can break remote management. In an elevated command prompt on the affected server, run:
If a proxy is configured, remove it for testing:netsh winhttp show proxy
This is a test step to confirm whether the proxy is the cause.netsh wintthp reset proxy - Review WinRM Group Policy settings On the affected server, check: Computer Configuration > Policies > Administrative Templates > Windows Components > Windows Remote Management (WinRM) Temporarily removing WinRM-related GPO settings can be used as a test to determine whether policy is blocking or misconfiguring remoting.
- Check WinRM operational logs In Event Viewer on the affected server, review: Applications and Services Logs > Microsoft > Windows > Windows Remote Management > Operational This is the primary place to look for WinRM errors that explain why Server Manager cannot refresh data.
- Check for HTTP SPN conflicts if Kerberos is failing
If the issue is intermittent, affects FQDN connections, or shows Kerberos-related failures, check whether default HTTP SPNs are registered to a service account:
If the SPN is found but the server name is not in the highlighted field of the error, configure a dedicated WinRM SPN with the port and machine account:setspn -q HTTP/servername.or.fqdn
If connecting through PowerShell remoting, use:setspn -s HTTP/servername.or.fqdn:5985 servernameEnter-PSSession -ComputerName servername.or.fqdn -SessionOption (New-PSSessionOption -IncludePortInSPN) - If WinRM returns status 500 This usually means WinRM could not process the request. Confirm that remoting is enabled, the WinRM listener accepts requests, and check event logs for related errors such as file access problems.
- Understand what Server Manager is trying to collect Server Manager thumbnails and manageability status depend on whether the server is accessible, whether the signed-in account has sufficient rights, whether required remote-management software is available, and whether the server is configured to be queried remotely. Event data shown in Server Manager also depends on successful event log retrieval.
If the issue remains after these checks, collect the following before escalating:
- Windows Server 2022 version/build using
winveror:(Get-ComputerInfo).OsVersion - Event data from:
- System
- Application
- Microsoft-Windows-Storage-Diagnostics/Operational if relevant
- Output of:
Get-Disk | Format-List
- Add Servers to Server Manager
- Errors when you run WinRM commands to check local functionality in a Windows Server
- Unable to install RDS deployment or add RDS roles
- Windows Admin Center known issues
- View and Configure Performance, Event, and Service Data
- Can't take a disk offline in a standalone Windows Server 2022 VM
