Installing this Service Pack does not change your current encryption level. Setup determines the encryption level of your operating system, either standard (56-bit) or high (128-bit) encryption, and automatically installs SP1 with the same encryption level. After SP1 is installed, if you want to change your encryption level from 56-bit to 128-bit, install the Windows 2000 High Encryption Pack. (If you decide to install the Encryption Pack before installing SP1, be sure to restart your computer before installing SP1).

SP1 Checked Build Files
Recommended for system administrators and other advanced users. The Windows 2000 SP1 Checked Build is a separate version of SP1 and should not be installed in addition to the SP1 Web download or the SP1 CD.
The Checked Build is a compiled set of files that include debugging information, providing administrators with specific details about program functioning. The Checked Build files are not required for proper operation of your computer.

SP1 Customer Support Diagnostics Update
Recommended for system administrators and other advanced users. The Windows 2000 SP1 Customer Support Diagnostics Update is included on the SP1 CD, but is not part of the SP1 Web download.
The SP1 Customer Support Diagnostics Update provides the updated symbols for diagnosing Windows 2000 system problems. The Customer Support Diagnostics Update is not required for proper operation of your computer.

Terminal Services Advanced Client
The Terminal Services Advanced Client (TSAC) is available on the Windows 2000 SP1 CD in the 'valueadd' directory, and is not a component of SP1 itself. As such, the TSAC is not included in the SP1 Web download, but it can be downloaded separately from the TSAC download page. The TSAC is a Win32©-based ActiveX? control (COM object) that can be used to run Terminal Services sessions within Microsoft Internet Explorer.
