我用ＩＩＳ发布后，也是不能登录 ，求哪位大哥帮帮我，在线等后 --------------------编程问答-------------------- http://www.chinaitpower.com/A/2004-04-14/77515.html

按照我的出现的Exception，我的解决方法如下：
1、在SQL Server创建 “电脑名\ASPNET”用户。比如我创建HP-2V47VI88M4GB\ASPNET
2、在SQL Enterprise manager里打开“安全性”文件夹，右击“登录”，选择“新建登录……”。“常规”选项卡，“名称”填HP-2V47VI88M4GB\ASPNET，其他默认；“数据库访问”选项卡，指定访问的数据库，我指定的是Northwind数据库，然后给他赋权限：dbo,public就够了。 --------------------编程问答-------------------- http://topic.csdn.net/t/20031001/09/2319314.html
