Query: An honest and frank review from an exprienced user

I have been using Citrix's WinFrame for about two years now in an administrative capacity. I began using v1.6 and then v1.7 and have seen a whole host of issues raised throughout my experience with the product. Trefil's book certainly covers the basics in more or less complete fashion, albeit in a less logically organised manner than would be ideal. But it does cover most of what a new user/administrator needs to be aware of at the outset. It in no way attempts to delve into what 'really' goes on in the day to day troubleshooting process or provide a 'resource kit' style coverage, as with Microsoft's Windows Resourse Kits - if one purchases the book for this reason, they will be disappointed. However I found the book insightful and useful just the same. I would like to have seen more concise troubleshooting methodologies included.
