禁用NetBIOS。打開本地連接的“屬性→Internet協議IP）→屬性→高級→WINS→禁用IP上的NetBIOS”（如圖3）。這樣一來就關閉了137、138以及139端口，從而預防IPC$入侵。


screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window CTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://tech.ccidnet.com/col/attachment/2005/7/474247.jpg');}" src="http://tech.ccidnet.com/col/attachment/2005/7/474247.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window CTRL+Mouse wheel to zoom in/out';}" border=0>

設置完必后，使用命令查看＂c:>netstat -an | find "137" ＂
＂c:>netstat -an | find "138" ＂
＂c:>netstat -an | find "139" ＂
