如图所示，在安全性-登陆里可以看到右边列表里的用户，选中用户右键-属性可以更改用户密码，及数据库角色等。
查看用户名，及密码是否正确，可以单独登陆 查询分析器
如果能登陆说明设置正确，在mssql搭建的asp cms里经常要用到用户名，密码。
现在看每个数据下面的用户选项，如图
选中一个一个数据库，或下面的用户选项可以 “新建数据库用户”
要注意的是登陆名必须在  "安全性-登陆"里有，并且，不能用默认的登录名，如sa ......

SQL SERVER 和EXCEL的数据导入导出
1、在SQL SERVER里查询Excel数据:
-- ======================================================
SELECT *
from OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
'Data Source="c:\book1.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...[Sheet1$]
下面是个查询的示例，它通过用于 Jet 的 OLE DB 提供程序查询 Excel 电子表格。
SELECT *
from OpenDataSource ( 'Microsoft.Jet.OLEDB.4.0',
  'Data Source="c:\Finance\account.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...xactions
-------------------------------------------------------------------------------------------------
2、将Excel的数据导入SQL server :
-- ======================================================
SELECT * into newtable
from OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
  'Data Source="c:\book1.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...[Sheet1$]
实例:
SELECT * into newtable
from OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
  'Data Sourc ......
