Force SMB v1 on Windows 2008 Server

Discussion in 'Windows Server' started by Christophe CHESNEAU, Oct 13, 2008.

  1. Hello,

    Is it possible to force SMB v1 in 2008 Server ?
    I have 1 W2K8 Data server and 2 W2K8 TS with an old Windev application
    which use indexed file for it database and I have a lot of corruption in
    these file due to Opportunistic Lock.
    My problem is that in 2008 Server, the opportunistic locking couldn't be
    disable because of the version 2 of SMB.

    Could we limitate the Lanmanserver service to emulate uniquely SMB V1 ?

    Thanks in advance. Regards

  3. Hello Meinolf,

    Thanks a lot for your response. I try it immediatly, I hope mrxsmb1 and
    mrxsmb services under Windows 2008 understand the OplocksDisabled value (I
    put it in both services key).
    In my case, the 3 servers are in Windows 2008 (1 data and 2 TS) and its
    automaticaly use SMB2 by default.

    Thanks another time. I will give you a feedback if it works. ;-)
    Best regards.
