How to close a file using wmic

I want to be able to programmatically, forcibly close local open file handles on a Windows Server. This includes files and folders that are opened by users connected remotely via a network shared folder.

I have experimented using sysinternals "Handle" which gives me the list of open files. "Handle" can close files but it fails to close handles opened via a network share.

I can close files/folders using the GUI via computer management->sessions console, so I would imagine that it is possible to do using a "wmic" command. I haven't found any examples so far and haven't been able to figure it out from the wmic doc.

Any help would be appreciated Thanks

You can use the NetFileEnum and NetFileClose APIs to simulate a network error which will entice the system to close out the handles for you.

There is a sample on Raymond's blog: Forcing a file handle closed when it has been opened remotely.
