  Jordan ElliottAug 13, 2025
  First, ensure that your ZyXEL Communications Server is powered on and properly connected to the network. You can try to ping the server or use the NAS Starter Utility to locate it. Also, verify that you have initialized your ZyXEL Communications Server using the NAS Starter Utility. Double-check that you have entered your login name and password correctly. Confirm that the share exists and review its access settings. Check if the shared folder is a subfolder of another (parent) share. See if there are any existing mapped network drives to the ZyXEL Communications Server. Ensure that the volume in which the share resides exists and is not down or degraded. Finally, verify that you have the client for Microsoft networks installed and enabled in your network connection’s properties.

  First, make sure that the ZyXEL Communications Server is turned on. If you are trying to log in directly by typing the server name into your web browser’s address field, make sure you are using the correct server name as the web site address. The default server name is nsa221; if you have changed the server name, use the new one. Check the hardware connections and make sure the LEDs are behaving as expected.

- A
  Angela MartinezAug 20, 2025
  First, ensure that the ZyXEL Communications Server is turned on and connected to the network. The local user should attempt to ping the ZyXEL Communications Server or utilize the NAS Starter Utility to discover it. Verify if the share exists and possesses the correct access settings for this user. Examine the Access Control List (ACL) of read/write permissions linked to specific files and/or folders. Ensure that the user’s computer is not already connected to another of the ZyXEL Communications Server’s shares. Check if the share has an ANONYMOUS or EVERYONE access right. Determine if the shared folder is a subfolder of another (parent) share. Finally, verify if the user belongs to a group with conflicting access rights.
