False negative returned from WMI monitors

Have your WMI monitors been reporting down services when in fact your services are up? You may need to increase the default length of the RPCPingTimeout registry value so that you are given a longer chance to connect.

To edit the RPCPingTimout registry value:

1. Go to Start > Run > Regedit.exe
2. From the Registry Editor go to:
   HKEY_LOCAL_MACHINE\SOFTWARE\Ipswitch\Network Monitor\WhatsUp Engine\2007\Settings
3. Within the Settings folder, select RPCPingTimeout and right-click. From the right-mouse menu, select Modify.
4. In the Edit DWORD Value dialog, enter in a new value for the timeout and click OK.

Important: The default timeout is 5 seconds. We strongly recommend that you do not exceed a timeout of 30 seconds.

After making any changes to the registry, you need to restart the WhatsUp Engine.

To restart the WhatsUp Engine:

1. Go to Control Panel > Administrative Tools > Services.
2. Select Ipswitch WhatsUp Engine from the list of services and select Restart from the left side of the dialog.
