FreeBSD-安装多线程下载软件axel提速Ports安装
[ 2006/08/15 13:12 | by gOxiA ]
FreeBSD的方便之处在于Ports安装模式，他可以使我们获取最新版本的应用软件并且方便的安装在我们的FreeBSD系统上，可是当我们在使用Ports方式安装时，最痛苦的莫过于它的下载速度，现在我们可以借助axel来提速Ports，实际效果非常明显。
一、安装axel
二、配置make.conf
一、安装axel
# cd /usr/ports/ftp/axel
# make install
# make install
二、配置make.conf
# ee /etc/make.conf

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
