Licensing is probably the most dreaded component that administrators ever deal with. In MetaFrame XP environments, you need to work with both Citrix and Microsoft licenses, in addition to the licenses for your applications. Both MetaFrame XP and Windows 2000 Terminal Services have significant licensing provisions to ensure that licenses are paid for. Gone are the days when you could carelessly install applications and assume that the accounting department paid for them.
The only thing that changes faster than technology is the licensing of technology. For that reason, it is important to note that this licensing chapter was up-to-date when this book was printed. However, it's possible that the details of Microsoft or Citrix licensing have changed since then. You can find the latest details on the web at www.microsoft.com/licensing or www.citrix.com/licensing.
Because Microsoft Windows licensing and the MetaFrame XP licensing are so different, we will address each one separately in this chapter. We'll also look at how third-party applications are licensed in MetaFrame XP environments before closing this chapter with a real world case study.
