问题1、修改了系统登录密码，导致sqlserver启动失败。
是因为SqlServer服务启动时自动绑定了一个系统帐号，一般这种情况出现在administrator帐户以外的系统帐户登录系统的情况，因为默认SqlServer是不指定帐号的。
解决办法：鼠标右键单击“我的电脑”，“管理”，“服务和应用程序”，“服务”，右键单击“MSSQLSERVER”，选择“属性”，选择“本地系统帐户”或者选择“此帐户”，并输入新的密码即可。
问题2、设置了sa密码，却忘记了？怎么改呢？怎么改呢？老是忘记……唉
解决办法：用企业管理器，以系统帐户打开服务器，依次展开目录树“root/安全性”（注意：不是右键单击root选择“属性”里面的安全性啊！），左键单击“登录”，右键单击“sa”选择属性，看到“密码”了吗？？输入新的密码，在确认窗口再次输入新密码，确定即可。
