Can you guys help me out.... I've been revising for 70-219 using the Exam Cram 2 book from Que. The book states that Bind 8.1.2 is required for Srv and dynamic update support. A friend let me borrow his cbtnugget 70-219 video.. which tells me that the version of bind to support srv and dynamic updates is 8.2.1 Who was right... I did a google search for bind srv dynamic update the first page to come back is [URL="http://www.microsoft.com/technet/"]www.microsoft.com/technet/[/URL] community/columns/profwin/pw1200.mspx Which states 8.2.1 A KB article on MS web site states 8.1.2 Anyone have a clue who is right.... I'm about 90% sure is gonna be 8.1.2... Id like to be 100% before I sit the exam! Cheers, Ant
