将ASP.net网站从II6移到II7

我知道我可能做了一些非常错误的事情，但我将源文件从一台计算机复制到另一台正在运行的IIS7，然后访问该网站并得到这个错误：

Error Summary HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Detailed Error Information Module IIS Web Core Notification BeginRequest Handler Not yet determined Error Code 0x80070021 Config Error This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false". Config File \\?\C:\inetpub\wwwroot\mysite\mysite\web.config Requested URL http://localhost:80/mysite/mysite/default.aspx Physical Path C:\inetpub\wwwroot\mysite\mysite\default.aspx Logon Method Not yet determined Logon User Not yet determined Config Source 96: </modules> 97: <handlers> 98: <remove name="WebServiceHandlerFactory-Integrated"/> 

任何帮助感激！
