今天在转移WEBSITEPANEL的时候遇到以下问题，无法新建网站：
[8/16/2010 6:35:19 PM] ERROR: ‘Internet Information Services 7.0’ UpdateSite
System.NullReferenceException: Object reference not set to an instance of an object.
at WebsitePanel.Providers.Web.IIs70.SetWebSiteApplicationPool(WebSite site, Boolean createAppPools)
at WebsitePanel.Providers.Web.IIs70.UpdateSite(WebSite site)
at WebsitePanel.Server.WebServer.UpdateSite(WebSite site)
将BackupCatelog.xml文件中的对应<AspNetInstalled />字段改成<AspNetInstalled>2</AspNetInstalled>即可正常恢复。
