  • SMB v1, slow shared folders access and opportunistic Lock on Windows 2008

    Hello,

    Following to a migration on Windows 2008 Server and because of corruption of indexed sequential database files for old application (hyperfile), I deactivated SMB v2 between my 2008 servers (1 data, and 2 TS) with the
    procedure http://www.petri.com/how-to-disable-...erver-2008.htm.
    I 've done it in order to deactivate opportunistic lock and cache causing file
    corruption.

    Since these modification, all "old" applications (Hyperfile, dbase, Borland
    BDE, etc...) working on shared folders on the 2008 data server are very long
    (I think in file opening) even if the client computer is an XP which is SMB
    v1 native.

    Did anybody have a similar problem ?
    Is it possible to deactivate opportunitic lock and cache in SMB v2 ?
    Do you have any idea ?

    Thanks in advance. Best regards.
