I recently replaced one of my home computers. Both run Windows 7 Home Premium and are hard-wired to a router. A printer is also connected to the router and used by both computers. The router also connects to an Internet modem. First, I configured both machines with a homegroup, but I was annoyed by the fact that you cannot share a whole disk drive over a homegroup network. I then also configures a workgroup on both computers, and set up sharing on several disk partitions on both machines.
One computer (called Laptop) can see the whole network and I can access all shared disk partitions on the other (called Desktop, which is the new one). However, Desktop can see only itself and the printer on the network and therefore Desktop cannot access the files on Laptop.
Desktop uses Norton Internet Security (came with the new machine for 60 days free), Laptop uses Norton 360. Internet access works correctly from both machines. Both machines are single-user with administrator privileges, and all permissions have been granted for the shared partitions.
Can it be that one of the necessary services is not running on one of the two machines? Or what else can be wrong? I have used the Microsoft Network Diagnostic/Troubleshooter to no avail.
Thanks for any tips.
