Writing text to files on Windows

I seem to be having trouble being able to *write* text to a file within a Windows server. Does anyone know what needs to be done to get this to work? I've tried making sure that the direcories are set to the maximum permissions (read/write/execute) to anyone. Still doesn't work. I'm trying this: $fp = fopen("test.txt", "w"); flock($fp, 1); fputs($fp, "testing"); fclose($fp); and I've tried "a", "a+", "w+", and "w" and no results.
