Windows 2003 SP2 WMI Win32_PerfRawData_W3SVC_WebService Timeout Workaround

I noticed when adding a WMI performance counter i couldn't get the Webservice details. It gave me after long time a error. It was only by the Webservice instance, the rest of the WMI counters worked perfectly.

After digging i noticed that the listattributes.vbs is passing 'null' to the WMI counter and that resulted in a time out. By replacing the 'null' value by a '-' i recieved details from listattributes. So i came up with the following workaround. I just wanted to share it with you in case someone else has problems adding the Webservice counter under OpManager.

In ManageEngine\OpManager\conf\application\scripts\listattributes.vbs
Under Case 5 replace the following

                strComputer = Wscript.Arguments(0)
        strUsername = Wscript.Arguments(1)
        strPassword = Wscript.Arguments(2)
        strClass    = Wscript.Arguments(3)
        instance    = Wscript.Arguments(4)

With

                strComputer = Wscript.Arguments(0)
        strUsername = Wscript.Arguments(1)
        strPassword = Wscript.Arguments(2)
        strClass    = Wscript.Arguments(3)
        if Wscript.Arguments(3) = "Win32_PerfRawData_W3SVC_WebService" Then
        instance    = "-"
        Else
        instance    = Wscript.Arguments(4)
        End if
