When you apply Windows 2000 SP2, the Supports Tools are NOT automatically upgraded or installed.
The updated tools are available in the \Support\Tools\Support.cab file on the Windows 2000 SP2 CD-ROM, or you can download them from http://www.microsoft.com/Windows2000/downloads/recommended/sp2/default.asp.
You can get help on these tools by typing toolname /help at a CMD prompt, or from the Support Tools help file, W2rksupp.chm.
