It works for me on XP - further, I just checked the code, and unlike 
another XP specific problem, we aren't relying on a specific error code 
to detect this situation - so the current code looks OK.

A quick search through the web suggests that WNetGetUser() may fail if:
     * There are invalid characters or spaces in the Computer Name box.
     * There is no network client installed.

But I doubt that is your case.
