Setting up Scan to Network Folder

I have a LaserJet Pro 200 Color MFP n276NW running wirelessly.

I have set up a shared folder on a PC (win 7) that I set up and access from other machines.

When I try to test from the setup page of the printer I get

Cannot find the remote server. Check server name or use IP Address to connect. Check that the remote computer is turned on.

Any Ideas?
