Running a command-line app always fails   

No matter how I write this code to run things at a command line, it failes 
with "system cannot find the file specified."

        Dim watchProc As System.Diagnostics.Process
        watchProc = Process.Start("NET USE LPT2: /DELETE")

Even simply reducing the command to "NET USE" fails.
Runs perfectly fine at a command line (Start -> Run -> "cmd")

What gives? Using VS2008 here...
