The network redirector that ships with Windows Vista and higher uses the SMB2 file-sharing protocol, by default. Windows XP and lower used the older SMB file-sharing protocol. There are some bugs in the SMB2 network redirector in Windows Vista or higher that may affect the reliability of database operations in a file-sharing network environment where shared databases are being accessed directly by multiple users on multiple workstations.

The following hot fixes are available to fix these bugs:

KB2028965: Data corruption when multiple users perform read and write operations to a shared file in the SMB2 environment

KB2618096: Data corruption when one user on a computer that is running Windows 7 or Windows Server 2008 R2 updates a shared file that is open on multiple computers by using SMB Version 2

KB2646563: SMB2 directory cache is not updated correctly if a file is deleted in Windows 7 or in Windows Server 2008 R2
