A. Win2K introduces the Windows Installer format, the .msi file, which lets you deploy software via a group policy. In keeping with this new software deployment approach, Microsoft released an .msi file that you can use to deploy Win2K Service Pack 1 (SP1). You can download the .msi file from http://www.microsoft.com/windows2000/downloads/servicepacks/sp1/msi/default.asp. Once you've downloaded it, run the executable and copy the created update.msi file to the /update folder of your service pack distribution point.
If you downloaded SP1 via the Internet, you won't have the required folder structure. Use the /x switch with the downloaded file to extract the package (e.g., sp1network /x). Extracting the package will create the folder structure that includes the /update folder.
