伺服器訊息區塊(Server Message Block,縮寫為SMB),又稱網路文件共享系統(Common Internet File System,縮寫為CIFS, /ˈsɪfs/),一种應用層网络传输协议,由微软开发,主要功能是使网络上的机器能夠共享计算机文件、打印机、串行端口和通讯等资源。它也提供经认证的行程間通訊机能。它主要用在装有Microsoft Windows的机器上,在这样的机器上被称为Microsoft Windows Network。 经过Unix服务器厂商重新开发后,它可以用于连接Unix服务器和Windows客户机,执行打印和文件共享等任务。 與功能類似的网络文件系统(NFS)相比,NFS的消息格式是固定长度,而CIFS的消息格式大多数是可变长度,這增加了协议的复杂性。CIFS消息一般使用NetBIOS或TCP协议傳送,分别使用不同的端口139或445,目前倾向于使用445端口。CIFS的消息包括一个信头(32字节)和消息体(1个或多个,可变长)。
