I have one Win8 Pro and one Win7 Pro laptop that I just rebuilt in my home. I have a synology server and a Qwest DSL wireless modem acting as my network which is also where I get my internet from. Laptop1 (Win8) was able to map drives to the server (which shows up simply as a computer) but laptop2 (Win7) does not see laptop1 nor synology server. Both laptops CAN get to the internet just fine as they both logged in just fine to the network. Both laptops have file sharing on and both have 'network discovery' turned on.
