Section 3 - Configuration Network Access The Network Access settings allow you to assign users and groups to specific folders or volumes. By default, all volumes 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. Network Access Assign permissions for users and groups on Settings: the local network. Category: Determines whether the access rule will apply to a group or individual user. User/Group: Select the user or group for the access rule or you can select All Accounts. Folder: Browse to open and select the folder or directory you are controlling access to. Permission: Set the user or group permission to Read Only or to R/W: Read/Write. Oplock: Oppor tunistic 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 (off). By default, Windows Vista® has Oplocks enabled and cannot be disabled. If you are having network performance issues with applications sharing files from the DIR-685, you may try to improve performance by setting Oplocks to No (off). D-Link DIR-685 User Manual 62
