After applying hotfix 2585542 to SCOM 2007/207 R2 Universal Connector, the Universal Connector may stop from working.
The following error may appear in the SCOM 2007/207 R2 application event log:
“[Microsoft.SystemCenter.Interop.Framework.Modules.WSManModule] ERROR No providers could be contacted. Could not get update events. Cannot create WSManConfig for any providers”
Event ID: 1500, Source: OpsMgr Connector for HP OpenView Operations
To resolve this issue, please upgrade the SCOM 2007/207 R2 Universal Connector to the latest version (In the SCOM 2007/2007 R2 & Provider side).
Note: As a temporary workaround, you can uninstall hotfix 2585542. However, using this workaround you expose you network to security risks.
