PHP and querying remote registry in WMI

[lonewolf217]

I have two php scripts, one which queries WMI on the root\cimv2 namespace which works without a problem on remote systems.  I have another I am trying to use to query the root\default namespace to parse the registry and this one isn't working properly

 

Does anyone have any examples of how to do something like this ?  Google has been rather sparce on how to do this.  I would do this in powershell but unfortunetly the remote machines are across multiple domains and authentication can't be scripted in powershell 

 

This is the error I cannot get around

Call to a member function EnumKey() on a non-object

 

This means your trying to run something from something that is not an object. E.G, A class.

I have not used this before, though is $wmi an object?

I would say your call to ConnectServer() isn't working then, no idea why though. Id hate to be scripting anything on windows.
