    if we are no longer supposed to use smb1 why does my network only work when it is on


    spending hours to get the computers to see each other on the network...

    the best advice I can find is to turn on smb1.

    micro.... recommends that we don't use this because of security problems.

    network discovery and file sharing does not work without it. Please explain.

    I've had to fight this fight too many times. micro.... seems not to be able to make a network that will work consistently. I have to admit that using Linux has started crossing my mind more often.

    :)

    SMB1 disabled; No longer have access to mapped network shares via File Explorer

    As per Microsoft suggestion I disabled the SMB1 protocol to stave off Wcry type attacks. At the same time I made sure SMB2 protocol was enabled. Now, i can no longer access mapped network shares using File Explorer. To verify the situation I turned SMB1
    back on and was again able to use File Explorer successfully. The network drive is operating properly; I checked using the browser admin features over IP. At present SMB1 is still off and SMB2 is on.

    What must I do short of re-enabling SMB1 to allow File Explorer to access the network drive?

    M.B.

    Config; Windows 10 Pro - latest, Synology DSM - latest

    I disabled SMB1. My network computers are no longer listed. What can I do?

    Without working SMB 1 (e.g. by disabling it as suggested here), browsing for computers
    with shares using Windows Explorer will not work any longer (as expected). They are still available by using \\COMPUTER\... which, I guess, involves a DNS lookup, but they are not listed automatically.

    • What graphical or non-graphical (cmd, PowerShell) ways are there on Windows 10 to list remote machines which offer shares?
    • Does running with or without a Domain change the available options?

    SMB1 disabled, SMB2 enabled; Can no longer access network shares


    Hey All,

    After the recent Wanncry attacks I disabled SMB1 protocol as per the cautionary suggestions from Msft et al. Now I can no longer access my network shares via File Explorer. I am still able to access the network device using IP address via browser. However, the unifying and familiar Explorer remains stubbornly broken. When I turn SMB1 back on everything works ok. Any ideas how to fix File Explorer access while remaining somewhat protected. Mucho thanks in advance.

    M.B.
