One of the new features of Windows Server 2008 is TS Web Access. TS Web Access gives administrators the ability to publish applications to users via a web page (much like Citrix’s Web Interface). One of the requirements to use TS Web Access is the updated RDP client available in the beta versions of Windows Vista Service Pack 1 (SP1) and Windows XP Service Pack 3 (SP3). Fortunately, if a users tries to connect with an older client Microsoft gives you a way to direct them to a generic or custom web page for further instructions. The Terminal Services Team has posted a blog entry with detailed steps on how to do this. Following are the basic steps:

1. Open IIS Manager on the server that hosts the TS Web Access Web site. To do this, click Start, point to Administrative Tools, and then click Internet Information Services (IIS) Manager.
2. In the navigation pane of IIS Manager, expand the server name, expand Sites, expand Default Web Site, and then click TS. (By default, TS Web Access is installed to this location. If you installed TS Web Access to a different site, locate and then click the site name.)
3. Under ASP.NET, double-click Application Settings.
4. In the Actions pane, click Add.
5. In the Add Application Setting dialog box, do the following:
   • a. In the Name box, type rdcInstallUrl.
   • b. In the Value box, enter the target URL for the link.

Note To restore the link to point to the default URL, right-click the rdcInstallUrl application setting, and then click Remove.

Alternatively, you can use a text editor, such as Notepad, to directly modify the Web.config file for the TS Web Access Web site. By default, the path of the configuration file is %windir%\Web\ts\Web.config. To do this, under the <appSettings> section of the file, add an entry that is similar to the following, where URL is the target URL for the link:

<add key=”rdcInstallUrl” value=”http://URL” />
