在网上找到一篇关于FreeBSD网络优化的文章，特转记于此：

解决SBS2003关机缓慢
[ 2006/08/01 09:25 | by gOxiA ]
安装或重新安装Exchange2003是直接从CD2上并不是从SBS2003集成安装时，SBS2003系统在关机时会出现缓慢的问题大约为10分钟左右才能关闭系统，微软已经确认此产品存在这个问题。
解决方法：
1、打开注册表编辑器，并定为到“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control”；
2、修改“WaitToKillServiceTimeout”的键值为“120000”
3、退出编辑器并重新启动SBS2003
添加环境变量解决VirtualPC默认存储位置
[ 2006/08/01 09:16 | by gOxiA ]
VirtualPC在安装之后的所建立的VPC默认存储路径是在“我的文档”下，但软件并没有提供修改默认存储路径的功能，今天无意间在Niuke的Blog上看到了解决方法特转记至此。
解决方法：在环境变量配置中新添加一个名为“myvirtualmachines”的环境变量，路经则为要创建的VPC存储位置。
