Windows XP doesn't directly support installation of the Windows Server 2000 Administration Tools. Without the Windows 2000 Administration Tools, XP also doesn't support the Exchange System Manager. Thanks to the release of Windows Server 2003, you can now install the Exchange System Manager directly on your Windows XP system. The Microsoft Windows Server 2003 Administration Tools are supported under Windows XP, and you can run the Exchange System Manger under the Windows Server 2003 tools.
To install the Exchange System Manager on your XP-based system, make sure your Windows XP system is running service pack 1 or greater. Next, download and install the Exchange2000-KB815529-x86-ENU.exe package from Microsoft's Web site.
This update tricks the Exchange 2000 setup program into believing that the system has the Windows Server 2000 Administration Tools. To complete the setup, install the Exchange System Management tools, and install the Microsoft Windows Server 2003 Administration Tools (adminpack.msi). Once completed, you can manage your Exchange 2000 environment from an XP client without a Terminal Services session.
