      In Windows 2000, Microsoft created a new transport for SMB over TCP and UDP on port 445. This replaces the older implementation that was over ports 137, 138, 139.

      You can disable port 139 WINS/NetBT name resolution:
      Click Start | Settings | Network and Dial-up Connections.
      Click the local area connection that you want to be statically configured, and then click Properties on the File menu.
      Click Internet Protocol(TCP/IP), click Properties, click Advanced, and then click the WINS tab.
      Click Disable NetBIOS over TCP/IP.
      Click OK, click OK, and then click OK.
