Chapter 1
Why Java instead of a Microsoft Management Console (MMC) snap-in? Interoperability. Citrix also
makes a MetaFrame for Unix product. Although, at this time, MetaFrame XP for Unix isn’t out yet,
when it is released, the use of a Java-based management console will mean that you’ll be able to
manage Unix and Windows MetaFrame servers from the same interface.
Not only does the Citrix Management Console provide a unified interface for all server-
management tools, but you can also use it from a Windows computer that isn’t a terminal
server—even from a workstation. If you browse the setup CD-ROM, you’ll see that you can
either choose to install MetaFrame XP or you can install the console. If you install the console
onto a computer, you can manage terminal servers from that computer without using an ICA
license or terminal services client access license (TSCAL), even if you’re running the console
from a Windows OS that doesn’t come with a TSCAL. (As you’d expect, this management is
limited to the MetaFrame side of terminal services—there’s no backdoor into RDP management.
Nor will you have access to any tools not in the Citrix Management Console, such as ICA Client
Configuration.) Although the Citrix documentation states that the console will work on NT and
Win2K machines but doesn’t mention Windows 9x, I’ve successfully installed and used the
console from a Win98 computer. About the only drawback to the console is that, like many Java
applications, it’s a bit slow. But it’s not so slow as to be unusable.
The ability to manage a MetaFrame server remotely without logging onto the terminal server is a
greater advantage than it may originally appear. Every time you connect to a Windows terminal
server, you assign a Windows TSCAL to the computer you connected from unless that client
computer is running an OS that gives it a free built-in TSCAL (Win2K Professional for Win2K Terminal
Services, Windows XP Professional for .NET Server). TSCALs are independent of display
protocols—using ICA instead of RDP to connect to the server doesn’t prevent you from using a
TSCAL. Since TSCALs are more –or less permanently assigned to the computer to which they’re
originally given, remote administration of a terminal server can potentially seriously impact the
number of available TSCALs. Since the Citrix Management Console connects to the terminal server
outside of a terminal session, it avoids this problem.
To connect to a server, from the Start menu, select Programs, Citrix, Citrix Management
Console. When you start the console, name a server in the farm you want to connect to, provide
the name of a person authorized to log on to the terminal server, and supply the domain and
password for that person. You’ll log on to the farm you want to manage; all resources in the farm
will be available, not just those in the server you connected to. When you’ve successfully logged
on, you’ll see a screen like the one in Figure 1.6.
