添加文件操作权限
对于Acess数据库文件要有everyone或者asp.net用户的写入权限

[辰爸]

这是因为没有权限在临时目录里写文件而产生的。这种问题的原因：系统temp文件夹访问权限不够修改方法如下：进工具-文件夹选项-查看-把使用简单文件共享(推荐)，关掉。然后进windows/temp，单击右键选择-属性，你就会看到一个叫做“安全”的选项，添加一个everyone,权限设置为完全控制，再将你正在使用windows的用户也设置为完全控制，就OK了。

用ASP.NET的写的WEB程序，当访问量过多后，在登录时就会报错Unspecified error 0x80004005，是连不上数据库了，查找了相关原因，是服务器上IIS向临时文件夹写文件写满了，写不进去了，要重新启动一下服务器，或者要清理临时文件或者调整磁盘空间(用磁盘配额。给IIS帐号：Internet Guest Account在C盘足够大空间的写权限) 或者 把临时文件夹定义到别的足够大的磁盘
