NAS network mapping fails after update to windows 10 version 2004 or 2009 RRS feed

  • Question

  • I have 3 NAS running in my private network:

    1) D-Link ShareCenter DNS325, latest Firmware 1.05, no more update available

    2) Iomega (now Lenovo) StorCenter ix2-200, latest Firmware, no more update available, 

    3) QNAP TS-251+, Firmware 4.5.1

    I have updated 3 different PC’s to Windows 10 version 2004 and just a few days ago to Windows 10 version 2009. After the update the -under Win 10 version 1909- mapped network drives of the DNS325 and StorCenter ix2-200 (which are much older than the QNAP TS-251+) won’t reconnect with either error “network path not found” or “the local device name is already in use”.

    Essentially windows 10 version 2004 and 2009 do not recognize the 2 devices as NAS and they do not appear under “network” anymore. Under Win 10 version 1909 as well as all previous versions of windows everything ran fine.

    I can however, access both NAS by using a browser and type in their internal network address (192.168.1.xxx).

    I have applied the registry modification found under answers.microsoft.com Here is the instruction:

    <<Computer\HKEY_CURRENT_USER\Network\Z   or your drive letter, I deleted Z.

    Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Map Network Drive MRU   and delete the entry, (a, b, etc), for your drive.
    Then add the following after remapping your drive or else it will fail to connect after a reboot or shutdown.



    Smbv1 is also enabled under “turn on / off windows features”.

    I would be grateful to get a solution for this since I do not want to miss out on those important windows feature updates. Many thanks!
