Hi All,
We are facing an issue with Windows server discovery in ServiceNow after upgrading to the Zurich version.
For most of the Windows servers, the discovery status is showing:
"Active, couldn't classify: No WMI connection, now finished"
Observations:
- Issue started post Zurich upgrade
- Server IPs are reachable and marked as Active
- Failure occurs during the classification phase
- Issue is impacting majority of Windows server discoveries
- MID Server services are up and running
We would like to understand:
- If there are any known issues related to WMI discovery after Zurich upgrade
- Any additional configurations or compatibility checks required for MID Server/WMI
- Recommended troubleshooting steps or fixes for this scenario
Any inputs or similar experiences would be helpful.
