The connection worked fine for me with credentials Chris supplied, so I'm guessing there's some firewall or limiting factor either on his network or elsewhere. I sent some screen shots to Chris of what I have for SSMS and asked if he has the Express edition or Developer SSMS.

Chris, one more thought, have you used this laptop elsewhere to connect to SQL Servers? Can you try from another network as a test, even a Starbucks/hotspot?
