NetBIOS with DHCP options

NetBIOS over TCP/IP allows host name resolution for NetBIOS names over the TCP/IP protocol.

Windows 2000 uses NetBIOS over TCP/IP to communicate with earlier Windows platforms such as

Windows NT and Windows 9x.



Windows also supports direct hosting, which allows the Windows 2000 client to perform name

resolution using DNS directly over TCP/IP without NetBIOS. Windows 2000 clients attempt to

establish a connection with both NetBIOS over TCP/IP and direct hosting. Whichever method

succeeds first is the one you'll use.



You can disable NetBIOS over TCP/IP and force the Windows 2000 client to use DNS to improve

network performance if all the network computers to which the computer needs to connect are

running Windows 2000 or later.



You can take one of two approaches to disable NetBIOS over TCP/IP: disable it outright or

configure the computer to take its settings from a DHCP server. The latter is the default setting.

To configure the client, follow these steps:



Open the Properties for the network interface in the Network And Dial-Up Connections folder.

Open the Properties for the TCP/IP protocol, click the Advanced tab, and then click the WINS tab.



Select Disable NetBIOS Over TCP/IP to disable it outright, or select Use NetBIOS Setting From

DHCP Server if you want the computer to pull the NetBIOS setting when it renews its address

lease.

Open the scope on the DHCP server using the DHCP console.

Right-click Scope Options and choose Configure Options.

Click the Advanced tab, and then under Vendor Class, select Microsoft Options.

Select 001 Microsoft Disable NetBIOS Option and set Data Entry to 0x2.

Then, close the scope options and use ipconfig on the client to renew the lease.
