IIS Admin Service goes away after restoring a VHD / VPC Server

I recently had the unexpected pleasure of losing my IIS Admin server - altogether!!! Translate - 150% !!!

Now, before this - everything was going great - except. During an upgrade of MOSS (Microsoft Office SharePoint Server) I encounted an issue that forced me to restore a VPC image - essentially bringing over another copy of the VHD and firing the server back up.

Interstingly, during that reboot - which for all intents should have gone fine - I see a hoard of DSKCHK processes running. Invariably, something got out of wack on the NTFS volumn between my shutting the image down and bringing it back up. During the 'fixing' process - a number of files invaribly can become corrupt - and the Metabase.xml - the blood-life of your IIS Admin service - is no exception. SO

Check in C:/Windows/System32/Inetsrv and you'll find a 'History' folder. Within here - hopefully - you'll find fairly recent backups of the Metabase.XML and MBSchema.XML objects. Before doing the following - be sure to backup the existing Metabase.xml and MBSchema.xml from C:/Windows/System32/Inetsrv first.

Now, rename a recent backup from the 'History' folder - renaming a recently Metabase.XML object, and then a recent MBSchema.XML object. Copy / Paste each of these to the C:/Windows/System32/Inetsrv.

Ahh, not quite done.

Now do a IISRESET from a command prompt.

Hopefully this will get you back to where you need to be.

### 解决方案及原因分析 HTTP 错误 500.19 表明存在配置文件读取失败的情况,通常是因为 Web.config 文件存在问题或是必要的 IIS 模块未正确安装。此错误的具体表现形式为“无法访问请求的页面,因为该页的相关配置数据无效”,并附带 HRESULT 值 `0x8007000d`[^1]。 #### 配置文件问题排查 Web.config 是 ASP.NET 应用程序的核心配置文件之一,在其语法不正确或包含不受支持的内容时会引发上述错误。因此建议仔细检查 web.config 中是否存在拼写错误、多余的字符或其他可能导致解析失败的因素[^2]。 #### 缺失模块验证与修复 另一个常见原因是 .NET Core Hosting Bundle 或者特定版本所需的 ASP.NET Core Module V2 并未被正确加载至 IIS 上下文中。这可以通过以下方式确认: - 打开 **IIS管理器** - 寻找左侧站点列表下的 “模块(Module)” 功能项 - 确认其中列出了名为 `[ASPNETCoreModuleV2]` 的条目;如果没有找到,则意味着需要更新或重新安装对应的运行库[^5] 对于缺失的关键组件,可以从官方渠道获取最新版次的 [DotNet Hosting](https://dotnet.microsoft.com/en-us/download/dotnet/) 来完成补全工作。特别是当目标应用基于较新的框架构建(如 .NET 7),则应确保选择了相匹配的发行包进行部署前准备[^4]。 ```powershell # 使用PowerShell命令行工具来检测已安装的.NET SDKs 和 Runtimes Get-ChildItem -Path 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options' | Where-Object {$_.Name -like "*dotnet*"} ``` 通过以上措施往往能够有效缓解乃至彻底消除此类异常现象的发生频率。然而如果经过这些调整仍然遇到相同的问题,可能还需要进一步深入调查其他潜在因素,比如权限设置不当等。
