In a workgroup, administrators can configure Group Policy for computers, users, or both. The options for each are listed under the Computer Configuration option and the User Configuration option, respectively, in the Group Policy console (which you can access by selecting Run on the Start menu, and then typing gpedit.msc in the Run dia log box). The Computer Configuration options, shown in Figure 9-11, include several policies covered earlier (account policies and local policies). There is also a Software Settings option and an Administrative Templates option.

IIS authentication, when enabled, authenticates all requests for a folder regardless of the type of file being retrieved ASPNET authentication works very differently, however, and can authenticate only those requests that IIS passes to the NET Framework By default, IIS 50 with the NET Framework installed is configured to pass requests for files ending in the extensions asax, ascx, ashx, asmx, aspx, axd, config, cs, csproj, java, jsl, licx, rem, soap, vb, vbproj, webinfo, resx, resources, vjsproj, and vsdisco This means that requests for any other file will not be passed through ASPNET, and therefore cannot be controlled by ASPNET authentication Here is a practical example: Your company uses a public Web site to sell recipes written using Adobe Acrobat These PDF files are located in the /recipes/ virtual directory.

After you have created a profile, you can control generally how Windows XP treats profiles by using the same Hardware Profiles dialog box you used to create the profile. (Open the System Properties dialog box, switch to the Hardware tab, and then click the Hardware Profiles button to access the dialog box.) First, you can specify how Windows uses hardware profiles during startup. You have the following options:

It is important that you undock correctly, as it can cause some issues, such as not shutting off disconnected external devices, if you don t. First, look at your docking station to see if it has a button that you need to press in order to release the computer. If it does, press the button before undocking (refer to the manufacturer s documentation for more details). When you do, it is likely that Windows will go into Standby mode so that it can correctly reconfigure itself. See Also

Users should be able to download these recipes only after they pay a fee and the application assigns them a unique user name and password You created an ASPNET application that uses Forms authentication to verify users, and you configured the /recipes/ virtual directory to require Forms authentication by setting the <authentication> section of the virtual directory s Webconfig file appropriately However, after the first user purchases a recipe, he e-mails the URL of the pdf file to his friends, and other people are able to download the file directly without being authenticated This problem occurs because files with extensions that are not associated with the aspnet_isapidll file are processed directly by IIS, and therefore cannot trigger an ASPNET authentication event The pdf extension is not one of the extensions mapped to ASP.

NET; therefore, IIS retrieves the file from the context of its anonymous user account and sends the file to the user To overcome this, add pdf to the IIS extension mappings as described in the next section After this change is made, IIS will send all requests for files ending in pdf to ASPNET ASPNET will enforce authentication rules and redirect users requesting the file to the logon page To ensure the security of a virtual directory authenticated with ASPNET, map all file extensions of documents that should be protected to the aspnet_isapidll file The following sections show how to configure additional ASPNET file types in IIS 60 and config files..

GPOs linked to a domain apply to all users and computers in the domain. This is a powerful policy, so you should keep GPOs at this level to a minimum. The typical use for GPOs at the domain level is to implement corporate standards. For example, a com pany might have a standard requirement that all users and computers use the same password and authentication policy company-wide. This would be a perfect applica tion of a domain-based GPO.
