第二天在对象资源管理器下连接数据库报错(重启过)--08下想重现错误，没能成功
通过DAC连接重置max server memory，重启数据库服务，正常登录

1 sqlcmd -E -S 127.0.0.1,1434
2 sp_configure 'show advanced options',1
3 go
4 reconfigure with override
5 go
6 sp_configure 'max server memory',1024
7 go
8 reconfigure with override
9 go

--附DAC连接
1、单用户模式启动数据库
开启一个命令窗口，输入以下命令，并保持窗口打开

1 d:
2 cd D:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Binn
3 sqlservr.exe mssqlserver -m

查看返回的日志信息，找到类似下面两行

1 Server is listening on [ 127.0.0.1 <ipv4> 1434] .
2 Dedicated admin connection support was established for listening locally on port 1434.

2、使用DAC连接到数据库
在另一个命令窗口运行

1 sqlcmd -A -d master
2 sqlcmd -E -S 127.0.0.1,1434或
3 sqlcmd -Usa -Ppassword -S 127.0.0.1,1434
