对于任何重复，我深表歉意，但我感觉自己在第一个障碍面前失败了。
我有一台 MS SQL 2005 Server，它拒绝启动，而且我没有它的密码（包括“sa”密码），显然是因为主数据库已损坏（见日志）。我通过谷歌搜索错误消息找到了很多说明（见下文），例如这和这，但它们似乎首先都涉及到能够运行 SQL 命令。
运行sqlcmd并输入SELECT * FROM sys.configurationsp; (return)（按照链接 1）没有输出。运行sqlcmd -S DVTEL（其中 DVTEL 是配置管理器中找到的 SQL Server 服务之一）失败，并出现连接超时。
从配置管理器启动服务器时：Could not start the SQL Server (DVTEL) on Local Computer. For more info, review the system event log.
或者：
> NET START MSSQL$DVTEL /F /T3608 The SQL Server (DVTEL) service is starting. The SQL Server (DVTEL) service could not be started. A system error has occurred. System error 1067 has occurred. The process terminated unexpectedly.
