Event Details

Product: Windows Operating System
ID: 5606
Source: Microsoft-Windows-WMI
Version: 6.1
Symbolic Name: WBEM_MC_WBEM_REQUIRES_ENCRYPTION_ASYNC_DENIED
Message: WMI Service could not deliver results asynchronously for %1 namespace. The namespace is marked with RequiresEncryption but WinMgmt could not establish a secure connection back to the client computer. Ensure there is a trust relationship between the client and server computers so that the client recognizes the server computer account.

Resolve

Change the authentication level used by the WMI client.

Change the authentication level used by the WMI client to Pkt_Privacy and restart the script or application. For more information about how to set the default process security level in VBScript, see Setting the Default Process Security Level Using VBScript.

Verify

Be aware that the WMI service and the WMI repository are running properly. However, client scripts and programs accessing namespaces marked with "RequiresEncryption" must connect with an authentication level that is set to packet privacy.
