基本上，这个情况最可能发生在第一次执行 .Net work 2.0 ，原因不明，但底下的做法大致可以解决此问题：

1.首先开启「命令视窗」，并切换目录到 %SystemRoot%/Microsoft.Net/work/(%SystemRoot% 视你 Windows 安装目录而定，一般是在 C:/Windows)

2.执行 "net stop w3svc" 终止 w3svc 服务
3.切换到下层目录 v2.0.5.xxx
4.执行 "aspnet_regiis.exe -ua" 解除 .Net 安装
5.重新安装 .Net 到 IIS 中 "aspnet_regiis.exe -i"
6.重新启动 w3svc "net start w3svc".
