Here is a screenshot, and a briefer description of the solution:
If the "Remote Install" tab is not displaying for an RIS server in the Active Directory, and the Active Directory is on a Windows 2000 Server, it may be because the snap-in required to display the tab is not installed in Windows 2000 Server unless you have RIS installed on that server.
To install the required snap-in without installing RIS on the 2000 server, install (or reinstall) adminpak.msi. This file is located in the I386 folder on the Windows 2000 Server or Windows 2000 Advanced Server CD-ROM. If you don't have the CD, try a file search on the 2000 Server for "adminpak.msi". Adminpak is the Remote Server Administration tools snap-in.
