Laptop Connects to Wifi, Cannot find Network Computers

I just got a laptop for work, but can't get it to find our server so I can get to work files. If I use the RDC, I can get on the server.
I want to map the network drive so I have access to my work files no matter where I am at.
I know the IP to get on my work desktop from home, and i can connect directly to the server via RDC from home too.

How do I get my laptop to map a network drive when it can not find the server in the network?

Thanks
