NET USE command And Network Provider interface.

Question

When we command "net use" on command prompt, the result has four columns.

Status Local  Remote                   Network
OK     Z:     \\10.x.x.x\Public        Microsoft Windows Network
       X:     \\10.y.y.y\Public        My Network Redirector

The Microsoft Windows Network(SMB)'s Status has OK value, but we don't. It's just empty.
Nevertheress, our redirector works well.

We implemented NPEnumResource function in our Network Provider dll.
But I don't know how can I set the value(OK).
How can I do that?

Thanks
