Starting with the RC0 release of Windows Server 2008, Terminal Services Web Access (TS Web Access) requires the most recent update to the Remote Desktop Connection (RDC) client software. This updated version is available in the beta versions of Windows Vista Service Pack 1 (SP1) and Windows XP Service Pack 3 (SP3).

If you are taking part in a Microsoft Connect Beta program, you can download the beta versions of Windows Vista SP1 or Windows XP SP3 from the program Web page.

If you are not an administrator, and you are using TS Web Access at your workplace, contact your system administrator to determine whether your workplace is participating in a Microsoft Beta program. If it is a participant, your system administrator can help you to obtain the updated RDC client software.

Information for Administrators

When a user who has an older version of the RDC client tries to use TS Web Access, they receive an error message with a URL that points them to more information. The target URL of the link currently points to this article. You can modify the target URL by using an ASP.NET application setting. To modify the target URL, follow these steps:

Note To complete this procedure, you must be an administrator of the TS Web Access Web site.

  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%WebtsWeb.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” />
