Runtime Error

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

解决:  您要检查web.config 是否合格,有时候是粗心,xml文件不完整.导致的问题

原因2: asp.net版本问题.asp.net有asp.net 1.1和 asp.net2.0 两个版本.
解决:  请确定您网站asp.net需要 哪个版本支持.选择合适的服务器运行版本.我们默认是2.0的,如果需要升级到1.1请联系我们服务专员.
