Not familiar with WMI Explorer, but does it let you specify the ImpersonationLevel?
Try the folling VBScript (not tested) on the local machine. Then edit the strComputer = "." line to be the server name and execute remotely:
On Error Resume Next Dim strComputer Dim objWMIService Dim colClusterNodes Dim objClusterNode strComputer = "." Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate,authenticationLevel=pktPrivacy}!\\" & strComputer & "\root\mscluster") If Err.Number <> 0 Then WScript.Echo "ERROR : Failed to get WMI handle [" & Err.Description & "]" Err.Clear Else Set colClusterNodes = objWMIService.ExecQuery( "Select * from MSCluster_Node") If Err.Number <> 0 Then WScript.Echo "ERROR : Failed to execute WMI query [" & Err.Description & "]" Err.Clear Else For Each objClusterNode in colClusterNodes Wscript.Echo "Caption : " & objClusterNode.Caption Wscript.Echo "State : " & objClusterNode.State Wscript.Echo "Status : " & objClusterNode.Status WScript.Echo "" Next Set colClusterNodes = Nothing End If Set objWMIService = Nothing End If
