I have 1 desktop running Windows 7 Ultimate 32 bit and 1 netbook running Windows 7 Home Premium 64 bit. Homegroup only worked about 10% of the time so I dumped homegroup, disabled it. I figured I'd just share through the normal Start>Network window. But for whatever reason, the computers can see each other on the network, but more often than not, they cannot connect to each other. When I try to connect to the other by double clicking on it, the window hangs for a few moments and then says Windows could not connect to [computer name]. Diagnostics are inconclusive, and it seems randomly it will start or stop working and it is very annoying, never knowing whether sharing will work. I have a feeling it has something to do with ipv6 but I'm not sure what to do about it. The specific error given when I can't access the other computer is the network path was not found or "Windows could not find a computer or device named [computer name]" even though the computer is listed in the network. Anyone have any idea?

Hello,

Things to consider and need to be configured correctly on all those computers in your network so that they can communicate.

1.) Workgroup Name is all the same on all computers.
2.) Verify that Netbios is enabled.
Click Start, and then click Network. (Or you can click Start, type ncpa.cpl into the search box, and press ENTER).
Click on the Network and Sharing Center, and then click Manage Network Connections.
Right click on the Local Area Connection or the connection you are using.
Select the Internet Protocol version 4 (TCP/IPv4)
Click the Advanced button under the General tab.
Click the WINS tab.
Click the Enable NetBIOS Over TCP/IP button.
Click Ok.

3.) Firewalls/Security Software need to be disabled.
4.) File and Printers sharing needs be enabled and here's a guide.

Also, disable password protected sharing, do the following:
1. In the Sharing and Discovery section of the Network and Sharing Center window, click the down arrow next to Password protected sharing.
2. Within the Password protected sharing settings, click Turn off password protected sharing, and then click Apply

Hope this helps.

It seems that the problem is indeed a firewall, as I tried each of your suggestions one by one. But I use the exact same firewall on my desktop as I do on my netbook, eset smart security 4.2. Both have the exact same settings, but only the one on my netbook is causing intermittent issues.I disabled the firewall on my netbook and I could connect freely on both computers, even when the firewall on the desktop was enabled. Are there certain ports that I need to open that were possibly already opened on my desktop that aren't on my netbook? Ports that allow not only network discovery but actually sharing files?

And see at the moment it is working with both firewalls on. I am almost positive it is the firewall though because when it wasn't working, turning it on and off controlled whether it worked or not. This is an odd problem.

Navigate Eset's configuration, verify that all your computers have "Allow Sharing" enabled. There shd be an Advanced Setup option for you to tweak the settings.

Allow sharing is enabled on both computers, and I saw that the subnet wasn't automatically added on the netbook's trusted zone, so I added the subnet and just to be safe I added the netbook's IP to the desktop's trusted zone and vice versa, but no dice. I still have intermittent issues that are solved by turning off the netbook's firewall. Any other ideas?

By any chance do you have the Windows firewall enabled as well?

Yes, I enabled it because it wouldn't continue diagnostics on something if I had it disabled, but I have file and printer sharing checked as an exception on both PCs, and I don't think that would explain why turning off the eset firewall when I am having issues solves the problem. When I can't connect to the other PC, turning off the eset firewall solves the issue for both computers.

Create a UserName and Password on all your computers sharing resources in your network from Control Panel =>User Accounts. For ex. Comp1 has a Username of User1 and a Password of 1234, create the same Login to Comp2 and then Vice Versa. See if this helps.

That's already the case. The computers are named Ryan-PC and Ryan-NB and are both part of the same workgroup, and the username is Ryan on both and the password is the same on both.

Can you pls. provide me ipconfig /all info of those 2 computers? Here's the guide:
Click on Start => run and type the word cmd on the blank field. From the black screen, type the word ipconfig /all and press enter. Right click on the black screen choose Select All and Paste the results here.

Can you verify the DNS settings of all the computers, I see a 4.2.X.X and seems to be Public DNS's? May I ask why they are configured this way? Please check the LAN properties of all the computers connected to your router if DNS are set to Auto IP or Manual IP? I woud change these DNS's to Obtain DNS Automatically from the LAN Properties of each computer.

Only my netbook and desktop are set to custom DNS. The rest are automatic, including the IP of the computers/ Everything is DHCP controlled except DNS servers. I have them set like that because comcast DNS servers are terrible and do an automatic search when you type in a wrong URL which gets annoying. With my router, I have DHCP reservation, so the IPs of the computers don't change, they are constant.

Basically the only thing not automatic are my DNS servers on my netbook and desktop. The router is set to auto IP for DNS as are the rest of the networked computers on the network.

As long as you have your network secured with WPA or WPA2, I wouldn't worry about disabling your Security's Firewall. Windows built in Firewall is very good as well and I'm pretty sure that you have them enabled in your computers.

I can disable windows firewall because it's redundant to have that and eset, but I don't want to disable eset firewall because that disables protection while web browsing as well. I have it set to allow sharing on the home network and to trust the network, but it's only this firewall that's giving me issues.

What version of ESET do you have? I had lots of issues with the 3.x version firewall.
