# Network connection issues

For issues connecting the server to the network, check the following:

- Why is the Network connection light off
- The firewall is blocking the connection
- Check that the router is correctly configured for DHCP
- Check the network is set up properly for TCP/IP
- Check the network NetBIOS properties

Why is the Network connection light off

| To determine why the network connection light is off

1. Make sure that all the cable connections are correctly plugged in.
2. Make sure the router or switch has power.
3. Restart the router or switch (or unplug and plug it back in).
4. If you are using your own Ethernet cable, try using the Ethernet cable that came with the HP Media Vault.

| The network connection light alternates between blue and off

The server is intermittently connected to the network.

Check the cable connection between the server and the router (or switch).

The firewall is blocking the connection

If using a firewall program, configure it to allow any HP MediaSmart applications:

- HPMVTray.exe - HP Media Vault System Tray utility
- Cddib32.exe - NTI DriveBackup!
- Shadow.exe - NTI Shadow
- NASSelector.exe - Media Vault Selection Application
- NASDriveMapper.exe - NASDriveMapper Application

For instructions to unblock, see the software vendor's documentation.

For information about firewall blocking alerts, see You receive firewall blocking messages.

Check that the router is correctly configured for DHCP

The HP Media Vault comes automatically set to use a Dynamic Host Configuration Protocol (DHCP) server to dynamically assign IP addresses. Most router come with a built-in DHCP server.

Check that the router has the DHCP server correctly enabled. Refer to the documentation that came with the router for instructions on proper DHCP server configuration.

For information about configuring a router for remote access, see the following sections.
