Stock "dir" command in /sys/startup.ms doesn't work with the /net directory

[SinZ163]

with dir "/" it prints /usr and /sys but not /net

and dir (or dir ".") when in the /net directory, it will print Invalid path when it is possible to read files in the folder and write files into the folder.

Good catch! We'll get this fixed ASAP.
