系统升级到SERVER2008R2 有些地方和WIN2003区别很大 这里记下
1.IIS 2008已经自带了不需要再额外找安装包或者系统盘安装 只需要打开服务管理器“角色”中添加”“web服务器（IIS）”和"应用程序服务器" 即可.
2.装完web服务器 剩下的就是数据库了 WINDOWS上的经典数据库SQLSERVER 这里使用SQLSERVER2008 本身安装包就是32和64位都兼容的所以直接安装
安装时提示兼容性问题 需要安装后再安装SQLSERVER2008 SP1
3.由于我安装SQLSERVER2008时默认使用的是WINDOWS登陆 没有选择SQLSERVER 启动SA登陆后无法正常使用 经验证 修改为SA登陆模式后需要修改SA状态为启用 并修改密码后重启SQLSERVER服务 否则是无法连接的
