The Support Tools are not automatically installed when you install Windows 2000 SP4. Microsoft Windows 2000 Datacenter Server customers must contact their original equipment manufacturer (OEM) for information about how to obtain the updated Support Tools.

The updated tools are available in the Support\Tools\ file on the Windows 2000 SP4 CD-ROM. The Windows 2000 Support Tools Help file (W2rksupp.chm) is located in the file. This file includes a description of each file and its associated syntax, sample output, and notes. See this Help for specific usage information for these tools. For additional help, type toolname /help at a command prompt, and then press ENTER.

To download the updated Support Tools, visit the following Microsoft Web site: (

   15-Jan-2003  15:42   1,191,987   Replmon.exe

   04-Jun-2003  23:50   5.0.2195.6666      55,056   Repadmin.exe
   16-Dec-2002  16:24   5.0.2195.6624     115,984   Netdom.exe


This binary contains a fix for a problem that occurs when you use the /debug switch for Netdiag.exe. When you run netdiag.exe /debug, some of the IP addresses in the output stream are incorrect., for example, the first number of the IP address is incorrect. A new feature has been added to Netdiag.exe where a local administrator can now view a domain-applied IPSec policy. Before this tool was updated, Netdiag.exe required the user to be logged on as a Domain Administrator to access this functionality.


By default, Netdom.exe was changed so that security identifier (SID) filtering is turned on when an external trust is created. A message warns the user of this change. You can still turn off SID filtering using Netdom.exe. This change was required to make the forest the security boundary by default.
