Exception Details: System.Web.HttpException: The current identity (NT AUTHORITY\NETWORK SERVICE) does not have write access to 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files'.

是由于.Net 2.0和IIS安装顺序颠倒导致的，必须先安装IIS，然后再安装.Net 2.0。解决方案有二个，一 重新安装.Net 2.0，点击修复；二 命令行进入 C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727目录，运行aspnet_regiis.exe -i 重新注册.Net 2.0到IIS。
