The Network Monitor captures displayed in the chapters of the book were 
printed using various versions of Network Monitor that were available 
internally within Microsoft during the writing of this book. The text 
versions of the files on the companion CD-ROM were printed using the 
version of Network Monitor provided with Release Candidate 1 of the 
Windows .NET Server 2003 family. The display of the frames within the 
capture files on the companion CD-ROM depends on the version of Network 
Monitor you are using. For these reasons, there might be differences in 
the display of frame structure for the text in the book, when viewing the 
capture file with Network Monitor, and when viewing the text version of 
the capture file.
