可恶的MS,不小心安装的WINDOWS 2003 SE的自动更新，杯具了一整天，具体内容稍后添加。
症状：安装win2003 se的自动更新，重启后访问MOSS网站提示404错误，File Not Found
解决：查看事件管理器。
a) System Error
"The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{61738644-F196-11D0-9953-00C04FD919C1}
to the user NT AUTHORITY\NETWORK SERVICE SID (S-1-5-20). This security permission can be modified using the Component Services administrative tool."
按参考链接1指示，添加NETWORK SERVICE账户并赋予Local Luanch & Local Activation 权限。
b）Application Error
"The schema version (3.0.149.0) of the database WSS_Content on MOSSDEV1\OfficeServers is not consistent with the expected database schema version (3.0.151.0) on MOSSDEV1. Connections to this database from this server have been blocked to avoid data loss. Upgrade the web front end or the content database to ensure that these versions match."
按参考链接2指示,运行"psconfig -cmd upgrade -inplace b2b -wait -force".
psconfig 工具默认在C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN 目录下。
再次访问MOSS网站，一切OK。
