Query: Enterprise Active Directory Services, Notes From the Field

I bought this book based on reviews and my experience with it's 'cousin', "Exchange Server 5.5 Notes From the Field". It was more than worth the money spent! After having taken some of the MCP classes on Windows 2000 AD, this built on those skills with real world scenarios and the bandwidth analysis figures for most every kind of network traffic in Windows 2000 will make it a handy reference in the near future. One thing worth noting outside the technical references of this book are the discussions about project management skills and being able to facilitate the numerous teams required to make the migration to AD happen. Other topics covered are: NDS/LDAP integration, AD scpriting, UNIX/DNS migration/co-existance and Exchange Server integration with the ADC.
