Sql server 2005 express使用windows验证
环境： windows server 2003 +　sql server2005 express.
问题： 
  我新建了一个组webDBUsers, 新建了一个普通帐户ronio，然后把ronio添加到该组中。
然后再express中，
新建登录: create login domain\webDBUsers from windows with default_database=testDB
用户映射: create user webUser for login domain\webDBUsers

但是这样建了以后，我一ronio帐户登录windows server 2003,然后打开express，以windows验证方式登录，却出现了如下错误：
  login failed for user 'STUDYPON-QHTGGX\Ronio'

详细错误信息如下：
  ==================================

无法连接到 domain\SQLEXPRESS。

===================================

Login failed for user 'domain\Ronio'. (.Net SqlClient Data Provider)

我用了很多方法测试都不行，baidu google上搜了不少，好像很少用普通帐户登录express的文章，
希望哪位大侠能指点一二，万分感谢！

2005还没试过,关注,学习,接分.

Window认证分为两种。一种是本地模式，一种是域模式，你安装的时候先错了。建议你重新装一下SQL2005这样你可以知道在哪一步进行选择，以后就不会错了。简单方法：同时，你以域身份登录到本机，然后在2005的服务器配置给改一下就行了，具体的语句，你到网上搜吧，我要下班了，不好意思啊，

那你把登录模式设置成混合登录模式,然后使用指定的用户名和密码来登录不行吗?
