There are many ways to navigate to the Web management interface. If you are building a Web application within Visual Studio. NET 2005, you can open the Web Site Administration tool by selecting asp.net Configuration from the Website menu. If you are developing a Web application outside of Visual Studio. NET, you can navigate directly to the Web Site Administration tool by requesting a special page webadmin.axd. For example, if your application is located in a virtual directory named MyWebApp on your local computer, you can open the Web Site Administration tool for your application by entering the following URL in your Web browser.
Http://localhost/MyWebApp/WebAdmin.axd
You can also use this latter method to access the Web Site Administration tools for deployed applications.
Behind the scenes, the WEB Site Administration tool consists of a set of asp.net pages that use the standard Login controls discussed in the next section. These pages are located in the Inetpub/wwwroot/aspnet_webadmin folder. If, for some reason, these files are accidentally deleted from the server, you can reinstall them automatically by executing the aspnet_regiis tool. You can also use the Aspnet_regiis tool to control access to WEB Site Administration tools. For example, you can use the Aspnet_regiis tool to restrict access to the WEB Site Administration tool to the local server. can refer to: http://www.microsoft.com/china/msdn/library/security/dotnetsecurity/NewSecuFeaASPNET20.mspx?mfr=true
