最后發現是域賬號的問題導致的，電腦的sql server是前同事安裝的，但是安裝的時候，是用的他自己的域賬號。
我的域賬號嘗試登陸無法識別的。
處理方法，用之前同事的域賬號登陸電腦，然后連接上數據庫。然后把自己的域賬號加入到logins中。
SQL server 2008 15434 以及 15023
從數據庫刪除用戶的的時候，提示用戶已經登錄，不允許刪除
通過下面的查詢語句找到session編號
SELECT session_id
FROM sys.dm_exec_sessions
WHERE login_name = 'chuck'
然后強制結束session，其中67是我找到的編號
kill 67
=========================================
刪除用戶之后，重新創建用戶遇到的問題
在出問題的數據庫上執行這個命令
sp_change_users_login 'AUTO_FIX', 'chuck'
The row for user 'chuck' will be fixed by updating its login link to a login already in existence.
The number of orphaned users fixed by updating users was 1.
The number of orphaned users fixed by adding new logins and then updating users was 0.
多次 執行直到出現
The number of orphaned users fixed by updating users was 0.
The number of orphaned users fixed by adding new logins and then updating users was 0.
sqlserver附加數據庫失敗
我遇到的問題是，之前用的EntityFramework，添加數據庫，是以鏈接數據文件生成的。
鏈接數據庫后台是由EF做的
<connectionStrings>
<add name="SchoolDBEntities" connectionString="metadata=res://*/School.csdl|res://*/School.ssdl|res://*/School.msl;provider=System.Data.SqlClient;provider connection string="data source=LUJUNTAO\MSSQLSERVER2012;initial catalog=SchoolDB;persist security info=True;user id=sa;password=123456;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
</connectionStrings>
坑爹了，發現之前連接數據庫的時候，沒有用127.0.0.1，用的居然是LUJUNTAO\MSSQLSERVER2012
備注：
在"127.0.0.1"附加的數據庫和在"用戶名\數據庫實例"附加的數據庫是不一致的
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
連接局域網中的數據庫（remote database），遇到上面的錯誤。原因是本地配置的代理沒有bypass掉局域網的ip。然后還需要重啟一下機器
登錄失敗 18456
Server Name: .
Error Number: 18456
Severity: 14
State: 1
Line Number: 65536
State 1
Error information is not available. This state usually means you do not have permission to receive the error details. Contact your SQL Server administrator for more information.
最后發現是因為連錯了數據庫，
本地安裝了sql server 2008和sql server 2014，其中sql server 2008的連接是127.0.0.1，但是sql server 2014的連接應該是127.0.0.1\sql2014
用everything搜索，ssms.exe "C:\Program Files (x86)\Microsoft SQL Server\" 【ssms.exe是sql server management studio】
"C:\Program Files (x86)\Microsoft SQL Server\120\Tools\Binn\ManagementStudio\Ssms.exe"
登陸失敗 error 26
在連接數據庫的時候，需要顯示指定端口1433。
或者啟用SQL Server Browser
https://dba.stackexchange.com/questions/118458/connect-to-sql-server-without-specifying-port
如果sql server browser是灰色的，無法啟用。那么打開services管理工具，設置SQL Server Browser服務的啟動方式為Automatic()
