DISABLE NETBIOS

A workstation running the NetBIOS service on a network can be vulnerable to attack from outside sources. If you are not using a DX9000 Series
DVR, you should complete the following steps to disable the NetBIOS service in the Windows operating system. Note, however, that you should
contact your network administrator before changing any NetBIOS settings.
To disable NetBIOS, complete the following tasks; instructions are provided in the following sections:

Disable the NetBIOS setting in the Advanced TCP/IP Settings dialog box.

Disable the NetBIOS Helper in the Services window.
After completing these tasks, restart the workstation.

CAUTION:

The NetBIOS service is required for the DX9000. Do not complete this procedure if you are using a DX9000 Series DVR or if any
other applications in your system require the NetBIOS service. You should follow proper security measures to limit the network’s exposure
to potential threats when the NetBIOS service is enabled.
