sql server2014显示sa无法登录的错误

Posted 2020-10-12 liu_xh

博主用的是sql serser2014，不过这个问题的方法也适用于2012等其他版本。

当用sa登录的时候，提示如下错误：

A connection was successfully established with the server, but then an error occurred
during the login process. (provider: Shared Memory Provider, error: 0 - No process is
on the other end of the pipe.)

(Microsoft SQL Server, Error: 233)

解决的办法是：
先用Windows Authentication登录，然后右击服务器的结点Properties->Security按如下图设置即可.
