Error 53 - Network Path was not found - batch-file

Question

first post of mine on this website, used to lurk but I've recently had a bit of a pickle with a batch-file
I've been working as a small little simple auto connect batch-command which auto-connects my laptop to my schools shared network server but for some odd reason I am unable to connect as the command prompt prints "System Error 53 has occurred The network path was not found."
If anyone could shed some light as to what I'm doing wrong would be much appreciated.
