Index.dat files are not deleted from the server when a user logs off a Terminal Services session to a Windows Server 2003-based computer

You configure roaming profiles for users on a Microsoft Windows Server 2003-based computer that is running Terminal Services. When a user logs off a Terminal Services session to that Windows Server 2003-based computer, Index.dat files are not deleted from the server.

This issue occurs if the following conditions are true:

• The Domain Name System (DNS) Client service is disabled on the server.
• Open file handles to the Index.dat files prevent the Index.dat files from being deleted from the server.

To resolve this issue, start the DNS Client service on the server. Additionally, configure the DNS Client service to start every time that the server starts. To do this, follow these steps:

1. Click Start, point to Administrative Tools, and then click Services.
2. Expand Services and Applications, and then click Services.
3. In the list of services, double-click DNS Client, click Automatic in the Startup type box, and then click Apply.
4. Click Start, and then click OK.
