Networking Problems

I just got one of the teams laptops to program on, and i’d like to have this connected to my desktop computer so I can share files, etc. I am able to get a wireless connection to my router, so I can get an internet connection on the laptop. I looked up the IP that was assigned to my desktop by my router (192.168.1.100) and am trying to connect to that IP via the command prompt. Here’s the command im using and the error messages.

net use \192.168.1.100\ipc$
System error 53 has occured.
The network path was not found.

Whats wrong?
