解决办法：

1)：出现这个问题呢，首先我们打开服务器看本地能不能登录sa数据库，如果本地也登录不上或者报错18456错误的话,请查看下面的方法

 http://www.cnblogs.com/yangxiaofei/p/4956792.html

2): 在本地如果可以登录Sa的话，那么就是网站的数据库连接时错误的，数据库的连接代码如下：

 <add name="ConnectString_Local" connectionString="server=.;uid=sa;pwd=yisiman@htu.cc;database=zlh_db;"/>

ASP的网站数据库连接一般都在网站根目录的web.config。我碰到这个问题的时候就去看web.config文件，看web.config文件里面有没有这个代码

可是最后找了一番下来还是没有发现 <add name="ConnectString_Local" connectionString="server=.;uid=sa;pwd=yisiman@htu.cc;database=zlh_db;"/>这串代码

我的web.config文件如下：

<?xml version="1.0"?>

<configuration>

  <!--url rewrite-->

  <configSections>

    <section name="rewriter" requirePermission="false" type="Intelligencia.UrlRewriter.Configuration.RewriterConfigurationSectionHandler, Intelligencia.UrlRewriter" />

    <sectionGroup name="NSW">

      <section name="HttpCompress" type="NSW.Web.Module.Configuration" />

    </sectionGroup>

  </configSections>

        <add mime="text/html" />

           <ExcludedMimeTypes>

               <add mime="text/html" />

           </ExcludedMimeTypes>

           注意：ExcludedMimeTypes及IncludedMimeTypes只需要配置一个就可以，如果像上面那样配置ExcludeMimeTypes的话，则表明除html类型的资源外，其它资源都会被压缩-->

      <ExcludedPaths>

        <!--设定不启用压缩的页面路径，下面设定了nocompress目录下的default.aspx页面将不会启用压缩功能,但其它页面则正常启用压缩-->

        <add path="/Manager/" />

    </handlers>

    <urlCompression doDynamicCompression="false" />

  </system.webServer>

</configuration>

通过仔细找我发现我的web.config文件里有 <connectionStrings configSource="Config\ConnectionString.config"> 这一行

接下来我就去找Config目录下的connectionString这个配置文件，打开后还真的发现事这个，代码如下：

<connectionStrings>

  <add name="ConnectString_Local" connectionString="server=.;uid=sa;pwd=password;database=test_db;"/>

</connectionStrings>

从上面代码可以看出来sa的登录密码和连接数据库，这样我们看下pwd密码和我们的密码是不是一样的，不一样修改成你刚才sa的那个密码就可以了，这样子网站打开用户没法登录SA的错误就解决了~！
