  • Hi,


    This issue can occur by incorrect network settings or incompatible third party programs. To troubleshoot the issue, please perform the following steps.


    1. Write down the network computer’s IP address. Click Start button in Windows 7 and type \\IP address, and then press enter. Can you access the network computer now?


    If it works, the issue can be related to DNS. You may check Hosts file. Please refer the following article.


    Modify the Hosts file 


    In the hosts file, ignore all the lines that start with *, and pay attention to other lines. Please only keep the line "localhost", delete others.  


    Otherwise, please move on the next steps.


    2. Restart the machine in Safe Mode with Networking and access the network machine again.


    3. Assure the following services are started: Computer Browser, Server, Workstation


    4. Modify relevant settings on Windows 7 machine.


    a. Click Start and open Control Panel.

    b. Open "Network and Sharing Center" and click "Advanced sharing settings".

    c. Expand the current network profile (such as "Home or Work"), and then select the following options:


    "Turn on Network Discovery",

    "Turn on file and printer sharing",

    "Turn on sharing so anyone with network access can read and write files in the Public folders",

    "Turn off password protected sharing"


    Hope this helps.
