Windows Server 2008 build 5259

Windows Server Codename Longhorn build 5259 was released on 2005-12-07 and it was distributed to TAP members.

You can install this build using the Build 5270.9 server key in the Windows Vista Build 5259 DVD.

This is the first leaked build to include the Server Manager console.

This build is extremely buggy; the Microsoft Management Console crashes upon selecting an item, you cannot access the Administrative tools from the Start Menu, and logging off has a chance of generating a STOP error.
