从Windows Vista开始,Windows中的TCP半开连接数限制就被禁用了,这样一来,系统想建立多少TCP连接就可以建立多少TCP连接。那么,出于安全考虑,用户如果想要启用TCP半开连接数限制的话,就需要手动添加注册表键值了,步骤如下,适用于Windows Vista/Serve 1. 开始菜单 - 运行 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ 注意: 在Windows 7下, 用户必须右键 - 新建dwORD (32-bit) 值,并命名为EnableConnectionRateLimiting. 禁用Vista/Win7中的TCP半开连接数限制 步骤如下,适用于Windows Vista/Server 2008/7。 1. 开始菜单 - 运行 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ 4. 在右侧面板中找到EnableConnectionRateLimiting
附部分原文: Starting from Windows Server 2008 and Vista SP2 (Service Pack 2), the incomplete simultaneous or concurrent half-open outgoing TCP connections limit is disabled by default. The new behavior allows as many as unlimited half-open TCP connections to be created
2. 输入regedit
3. 找到并双击如下键值:
Tcpip\Parameters\EnableConnectionRateLimiting
4. 将其值设为1
5. 重启系统
