Rightly or wrongly, Citrix is the dominant player in the SBC (Server Based Computing) market. When you say "Thin Client" people automatically assume you’re talking about a Citrix product. There are alternatives which are often cheaper and often sort out the biggest difficulty that Citrix has failed to even get close to resolving: printing. I will give them credit for one thing, they’ve got the best MOM 2005 management pack that I’ve seen.
Anyway, Citrix has posted a number of training videos on their site for Presentation Server 4:
- Optimizing Printing in Presentation Server 4 environments
- Configuring Policies in Presentation Server 4
- Understanding and Designing Citrix Presentation Server 4 Farms
- Deep Dive into Citrix Presentation Server SpeedScreen Technologies
- Fundamentals of the Citrix Presentation Server Architecture
- Licensing Essentials
- Migrating your Microsoft Windows Terminal Servers to a Citrix Presentation Server Farm
This might help make up for the apparent lack of literature on this important infrastructure and business product.
