Windows 8.1 clients can't connect to SMB 3.02 shares (Windows Server 2012 R2) RRS feed

  • Question

  • We have found recently that our Windows 8.1 clients are unable to connect to Server 2012 R2 shares (SMB 3.02). When trying to browse to them in Explorer we get "Windows can't find <UNC path>". Windows 7 clients can still connect to these shares, only our 8.1 clients are affected. Attempting to access using the IP address instead of the host name makes no difference.

    The 8.1 clients can still connect to shares on 2008 R2 servers. Server 2012 R2 to Server 2012 R2 also works.

    No changes have been made to the clients or to the group policies which control them that could readily explain this issue.

    Any advice on where to start troubleshooting this would be appreciated.

  • Thanks for your reply Simon. I tried everything you mentioned and it made no difference. However, after a few days, shares on all Windows Server 2012 R2 servers for all 8.1 clients have started working again without any further changes.

    It is a bit worrying that this has happened without us being able to understand why.

  • Hi,

    There are many reasons could cause the issue. I would like to suggest you follow the steps below to troubleshoot.

    1. Open command prompt as administrator, try to ping the IP address of the Windows Server 2012 R2. If it is failed to ping, it is probably the network issue, and please check the network connection. If it can ping successfully, please continue to try the steps below.  

    2. Try to disable the Windows firewall. If you have any anti-virus software installed, please uninstalled them temporarily due to the anti-virus may block the connection. Then start the Windows in clean boot mode to check if any 3rd party software has a conflict. After that, check the issue again. If it still failed, install the anti-virus software back and try the step below.

    3. Open command prompt as administrator, run the command below to reset Winsock catalog.

    netsh winsock reset

    In addition to that, have you tried to map the folder as a drive? Please tell us whether it works.

    Good luck to fix it.

    Best Regards

    Simon
