I have recently migrated from NT 4.0 to W2K with active directory. The first W2k server is the mail server &nbsp;and the first Active directory domain and is also setup as pre-windows 2000 mode. Now I've added an additional domain controller, but if the first one is down, it takes 15minutes to login. Any ideas? Is there more work to be done? Do I move the server to native mode and are there any implications?<br />

Windows 2000 is an operating system for use on both client and server computers. It is the successor to Windows NT 4.0, and is the last version of Microsoft Windows to display the "Windows NT" designation. Four editions of Windows 2000 were released (Professional, Server, Advanced Server, and Datacenter Server) that shared a core set of features, including many system utilities such as the Microsoft Management Console. All versions of the operating system support NTFS 3.0, Encrypting File System, as well as basic and dynamic disk storage. The Windows 2000 Server family includes support for Active Directory services, Distributed File System and fault-redundant storage volumes.
