DFS node status checking

Hi,

I run the attached vbs code (from MS Script Center) to check DFSnodes properties in my domain DFS root. Properties are displayed OK, I'm focused especially on State/Status of each node. The 'State' for each node is '0' (OK), 'Status' is empty.
When I make any of DFSnodes inaccessible (for ex. by shutting down the server hosting that node's only DFStarget) and run the script again, State/Status show always the same values, like if the node was still ONLINE, but it is in fact OFFLINE! (easy to confirm in GUI DFSconsole)
I don't understand what's wrong, or what are the Status/States properties good for then :-(
Or is there another script way of realtime checking DFSnode's state ?

Thanx for any help
George

For each objDfsNode in colDfsNodes
Wscript.Echo "Caption: " & objDfsNode.Caption
Wscript.Echo "Description: " & objDfsNode.Description
Wscript.Echo "Install Date: " & objDfsNode.InstallDate
Wscript.Echo "Name: " & objDfsNode.Name
Wscript.Echo "Root: " & objDfsNode.Root
Wscript.Echo "State: " & objDfsNode.State
Wscript.Echo "Status: " & objDfsNode.Status
Wscript.Echo "Timeout: " & objDfsNode.Timeout
Next
