Tools and Techniques



This section provides suggestions for and information about alternative troubleshooting tools and techniques.



Ping Your NAS System



If you are unable to connect to the NAS system using the NAS Manager, try to ping the NAS system. From a client system, click the Start button, click Run, and

then type cmd. At the command prompt in the cmd.exe window, type ping system_name, and then press <Enter>.





If you can ping the NAS system but cannot access it through the NAS Manager, your NAS system might still be booting into the Windows®Storage Server

2003 operating system and might not have started the Microsoft®Internet Information Services (IIS).





My Network Places



If you have a client system running Windows 2000, Windows 2003, or Windows XP on the same subnet as the NAS system, double-click My Network Places.

Browse through the network and locate your NAS system.



System LEDs and Beep Codes



If your NAS system is not booting or responding properly, you can diagnose some problems using the system's LEDs and beep codes. For more information

about the LEDs and beep codes, see your system's Installation and Troubleshooting Guide.



Remote Desktop



You can use the Remote Desktop to connect to your NAS system from a client system. You can access Remote Desktop through the NAS Manager.



To access Remote Desktop from the NAS Manager, perform the following steps:

1. Log in to the NAS Manager.

2. Click Maintenance.

3. Click Remote Desktop.

4. Enter the administrator user name and password and click OK.



NOTE: The default system name is DELLxxxxxxx, where xxxxxxx is the system's service tag number. For example, if your service tag number is 1234567,

type http://DELL1234567. You can also access the system directly through secure port 1279 by connecting to https://DELLxxxxxxx:1279, where xxxxxxx

is the system's service tag number.

NOTE: It may take several minutes for the NAS system to boot, depending on your configuration and the amount of storage attached to the system.

NOTE: The default administrator user name is administrator and the default password is

powervault.
