createfile

无法为此请求检索数据。（Microsoft.SqlServer.SmoEnum）其他信息执行Transact-Sql语句或批处理时发生了异常,Microsoft.SqlServer.ConnectionInfo）尝试打开或创建物理文件d:\Data\***.mdf时，Create file遇到操作系统错误5（拒绝访问。

【错误提示】

【问题背景】
数据库版本：SQL Server 2005企业版
操作系统版本：Windows Server 2003企业版
错误引发描述：数据库分离后，把数据硬盘从一台主机换挂到另一台主机上（两台主机的操作系统和数据库版本都是一样的）。结果附加数据库时，提示上面的错误。

【问题分析】
很明显，是文件操作权限不够引发的问题。

【解决方法】
即可解决问题（网上的资料都是这么说的）。给什么用户添加权限呢？比如：Administrators用户组、NETWORK SERVICE、MSSQLUser或Everyone，具体用哪个，看你的SQL服务是哪个帐户启动的，如果不清楚或者懒一点，可以直接添加Everyone用户。本来想上个截图的，不知道为什么，几十Kb的图片，一直上传不成功。

【意外情况】
可能你通过上面的解决方法，给数据文件所在的文件夹添加了相应的用户和操作权限，但问题依旧（这也正是我纠结痛苦的地方，网上都是那么说的，咋就不行哩~~？？！）。最后我的解决方法是：。问题终于彻底得到解决。原因应该是文件夹的权限没有自动继承到里面的文件上。
