Offline files causes slow Windows Explorer RRS feed

  • Question

  • We recently have been upgrading users from Windows 7 to Windows 10. Since upgrading users they have started experiencing extremely slow delays sometimes (majority of the time) with Windows Explorer. I have personally seen where opening "This PC" could take up to 5 minutes to render all the local and network drives. They access a file server over a VPN but have never had an issue until we started upgrading to Windows 10.

    To try to resolve this issue we attempted to enable the "Always Offline" mode with offline files and that has improved their Windows Explorer experience, however we now are faced with yet another problem. It appears at times the network drives will random disappear or go into a disconnected state, at which time we have them run a script to try to remap them.

    DFS is also in play here and we noticed when the drive goes into a disconnect state and they connect to the root DFS namespace, they can no longer see the share the mapped drive connects to. They can still see the profile share though.

    We do have a case open with Microsoft but it is going extremely slow. We have seen others on forums having what seems like the same issue which tends to lead to the solution that "Offline Files in Windows 10 sucks". We do see some warning/errors on the client machine such as "0x80070035 The network path was not found." which appears to be a very generic error. Network connectivity appears to fine at the moment of these warnings and I think it is Offline Files causing the issue.

    Any help would be appreciated.

  • After a long case with Microsoft we basically just ended with "That is just how it is". Windows 10 requires much less latency for offline files over a VPN than Windows 7 did. They claimed Windows 7 had the issue but it only occurred at a much higher latency (85ms +/-) but with Windows 10 they need more along the lines of 15ms or so which is hard to get sometimes.

  • We have found that the disappearing shares from the DFS root namespace was because it was checked to Work Offline. Now my assumption is this was checked because we have the "Always Offline" mode enabled because Offline Files causes Windows Explorer to be so dang slow.

    How do we make the DFS root namespace not have that work offline button if we have always offline enabled??

  • Hi,

    What's version of Windows 10?

    Now the latest build is OS Build 17134.228. Make sure it's up to date.

    And then reset the network via:

    • Select the Start  button, then select Settings  > Network & Internet  > Status > Network reset.
    • On the Network reset screen, select Reset now > Yes to confirm.

      Wait for your PC to restart and see if that fixes the problem.

    Note: After using network reset, you might need to reinstall and set up other networking software you might be using, such as VPN client software or virtual switches from Hyper‑V (if you're using that or other network virtualization software).

    In addition, we’d better also check the DFS server settings.  For DFS server we have a specific forum, they may have more suggestions for you.
