I have Windows 7 SP1 Ultimate 64-bit that struggles along to see the shared resources of other computers on the LAN even if the "Network discovery" and "Files and Printers Sharing" options of the "Advanced sharing settings" applet are enabled.
In other words, if I click on Network in Windows Explorer, no computer on the LAN is displayed; whereas, if I write "\\<ComputerName
>" in the address bar, I can see with difficulty its shared resources.
This fact is in each account.
I have no firewall active, I use the network of type "Work" and I do not use the homegroup feature.
The operating systems on the target computers are Windows 7 SP1 Ultimate 64-bit and Windows XP Pro SP3. The computers have the same time.
How can I check whether the SMB protocol is working properly?
How do I fix this?
