Can't see a PC's Shared Files on a Windows Network?

Ever have one PC on your home windows network that you just can seem to access the shares? Well here's some things to check:

1. Make sure the Windows Firewall is off
2. On the Exceptions Tab of the Window Firewall, make sure "File and Printer Sharing" has a check.
3. Disable UPnP. This is found in Add/Remove Programs >> Add/Remove Windows Components >> Networking Services
4. In the registry: "HKey_Local Machine/System/CurrentControlSet/Control/LSA" change "restrictanonymous" from 1 to 0

After you've done all that you should be able to access all the shares on the previously unsharable machine.
