are open to anyone on the local network with read/write access. Before specific user or group rules can be created,
the default rules must be deleted.

local network.

Opportunistic locks (oplocks) are a characteristic
of the LAN Manager networking protocol
implemented in the 32-Bit Windows family.
Oplocks are guarantees made by a server for
a shared logical volume to its clients. These
guarantees inform the Client that a file’s content
will not be allowed to be changed by the server,
or if some change is imminent, the client will be
notified before the change is allowed to proceed.
Oplocks are designed to increase network performance when it comes to network file sharing however when using
file-based database applications it is recommended to set the share oplocks to
No
.
By default, Windows Vista
®
has Oplocks enabled and can not be disabled. If you are having network performance issues
with applications sharing files from the DNS-323 you may try to improve performance by setting Oplocks to
No (off)
.
