SQL Server服务无法启动时，时常会遇到以下提示：
本地计算机上的MSSQLSERVER服务启动后又停止了。一些服务自动停止，如果它们没有什么可做的，例如“性能日志和警报”服务。
您可以打开“计算机管理”下的“事件查看器”，您会发现如下图中所示错误：
这时您可以检查日志文件C:/Program Files/Microsoft SQL Server/MSSQL.1/MSSQL/LOG/ERRORLOG文件，用文本工具打开后，您会发现类似如下的内容：2009-06-14 09:14:55.56 Server Microsoft SQL Server 2005 - 9.00.1399.06 (Intel X86)

2009-06-14 09:14:56.42 服务器 SQL Server could not spawn FRunCM thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.
这时，不难看出：
TDSSNIClient initialization failed ：TDSSNIClient 初始化失败。
SQL Server could not spawn FRunCM thread ：无法生成FRunCM 线程。
我们可以判定，可能会是以下问题，分别处理如下：
1、可能是IP地址配置不对。解决方法如下：
打开 /Microsoft SQL Server 2005/配置工具/下的SQL Server Configuration Manager，选择mssqlserver协议, 然后双击右边窗口的TCP/IP，在弹出窗口中检查IP配置。
一般来讲，默认的IP2是：127.0.0.1，如果第一个IP地址的端口1433端口ping不通的话，服务无法启动。您可以将127.0.0.1放在IP1上，那么不管IP2的端口是否能ping通，服务都能够正常启动。您也可以将IP1设置为当前机器的IP地址，并保证该IP地址的端口能够ping通。
2、可能是因为VIA协议启用造成的。解决方法如下：
打开 /Microsoft SQL Server 2005/配置工具/下的SQL Server Configuration Manager，选择mssqlserver协议, 然后右边窗口有个VIA，点击右键禁用它，点击“确定”即可。这时候再启动sqlserver服务即可！
另外，管理员密码修改也会造成sqlserver服务无法启动。解决方法如下：
打开 /Microsoft SQL Server 2005/配置工具/下的SQL Server Configuration Manager，打开SQL Server属性，如下图所示：
将本帐户的密码修改为您更改之后的管理员密码，“确定”即可。这时SQL Server服务应该就能正常启动了。
