I fixed the parameter parsing in this class in cases where you have the wrong number of arguments. This should solve the confusion encountered by the bug reporter. Marking as fixed in 15.

I'm not a Windows guy, sorry.
The only hard part of using WMI is creating and properly configure a non-domain admin account for accessing WMI on the Windows servers. Besides that, make sure the Windows Firewalls allows the OpenNMS to talk with it. It is Windows so it could be a lot of ports to open

I tried the the host ip and this is what i get. I can connect to this server from another windows server using power shell.

Thank you for your help

The error is pretty straight forward: "Caused by: java.net.UnknownHostException: server01: Temporary failure in name resolution". You should use a valid IP or FQDN of the Windows Server you're checking with the checkwmi command.
Also keep in mind that the "hard" part of monitoring Windows servers with WMI is at Windows side, not OpenNMS; specially if you want to use a non-domain administrator account to access WMI data.

WMI access seems to be working in the server (remote and local). I was following this guide (http://www.opennms.org/wiki/WmiConfiguration) and when i try to check the WMI from the opennms box i get this error.
