- Simplifying the transport of SMB traffic.
- Removing WINS and NetBIOS broadcast as a means of name resolution.
- Standardizing name resolution on DNS for file and printer sharing.
Direct hosted "NetBIOS-less" SMB traffic uses port 445 (TCP and UDP). In this situation, a four-byte header precedes the SMB traffic. The first byte of this header is always 0x00, and the next three bytes are the length of the remaining data.
Use the following steps to disable NetBIOS over TCP/IP; this procedure forces all SMB traffic to be direct hosted. Take care in implementing this setting because it causes the Windows-based computer to be unable to communicate with earlier operating systems using SMB traffic:
- Click Start, point to Settings, and then click Network and Dial-up Connection.
- Right-click Local Area Connection, and then click Properties.
- Click Internet Protocol (TCP/IP), and then click Properties.
- Click Advanced.
- Click the WINS tab, and then click Disable NetBIOS over TCP/IP.
To determine if NetBIOS over TCP/IP is enabled on a Windows-based computer, issue a net config redirector or net config server command at a command prompt. The output shows bindings for the NetbiosSmb device (which is the "NetBIOS-less" transport) and for the NetBT_Tcpip device (which is the NetBIOS over TCP transport). For example, the following sample output shows both the direct hosted and the NBT transport bound to the adapter:
NetBT_Tcpip is bound to each adapter individually; an instance of NetBT_Tcpip is shown for each network adapter that it is bound to. NetbiosSmb is a global device, and is not bound on a per-adapter basis. This means that direct-hosted SMB's cannot be disabled in Windows without disabling File and Printer Sharing for Microsoft Networks completely.
