The common context is:
net use (Letter): \\Computer Name\Share
I haven't used this with a computer, but I believe if you wanted to map to a folder on the C drive called Files on a computer named Computer to Letter M you would use the following:
net use M: \\Computer\C$\Files
Again, I'm not 100% sure on the C$ part, you might be able to omit that and just go with \\Computer\Files.
Good luck!
