Hi all, i have the following situation, two computers in a LAN using Windows 7. I can access Shares from computer A to B but not from B to A. I found that if i use the IP address instead of the computer name i could connect without problem(after write the proper credentials). I read in other forum question that maybe is the Host file that is wrong but i check that and almost don't contain relevant information. So what can be the problem? I also have problem using the HomeGroup function and i think is the same cause, the computer B can not see A using the Name. Firewall is disabled in A to avoid any connections issue.

Hi, What is the error message you received from HomeGroup? The issue is mostly DNS related. First, please update your network adapter to the latest version from the manufacture, then disable and enable the Local Area connection. If the issue persists, open an elevated cmd windows and type the following command one by one. ipconfig /flushdns netsh interface IPV4 uninstall netsh interface IPV4 install netsh interface IPV6 uninstall netsh interface IPV6 install It will reinstall your IPv4 and IPv6 Protocol. However, if it doesn't work, enable NetBIOS over TCP/IP for testing. 1) Go to "Control Panel -> Network and Internet ->Network Connections". 2) Right-Click on the connection and choose Properties. 3) Click "Internet Protocol (TCP/IP) Version 4" in the list. 4) Click Properties, and then click Advanced. 5) On the Advanced TCP/IP settings windows, go to "WINS" tab. 6) Under NetBIOS setting, click "Enable NetBIOS over TCP/IP", and then click OK.
