今天安装好了vista以后，直接把开发环境都转移下来，结果第一就出现了问题，把 customerrors 改为mode="RemoteOnly" 以后，出现如下的提示。

Server Error in '/web' Application.

Failed to access IIS metabase.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.Hosting.HostingEnvironmentException: Failed to access IIS metabase.

The process account used to run ASP.NET must have read access to the IIS metabase (e.g. IIS://servername/W3SVC). For information on modifying metabase permissions, please see http://support.microsoft.com/?kbid=267904.

Source Error:

Line 51: 						if ( HttpContext.Current != null )
            Line 52: 						{
            Line 53: 							config = WebConfigurationManager.OpenWebConfiguration("~");
            Line 54: 						}
            Line 55: 						else

于是想起一招，直接以管理员身分运行vs2005。如下图：　　（顺便show 一 show 我的桌面）

试了一下，果然好用，呵呵，以后就用这方法了。特此记之。
