It is recommended that you check
with your application vendor before running an application on Itanium-based servers to
ensure it will function correctly.
CHAPTER SUMMARY
This chapter covered some key changes to DNS and discussed the use of BitLocker Drive
Encryption to help protect the system. Windows Server 2008 natively supports IPv6.
As a result of this, Microsoft has had to enhance the functionality of DNS in Windows
Server 2008 to be able to accommodate IPv6 entries. Local-link multicast name resolution
(LLMNR) has also been created to address the need to resolve IP addresses of hosts on
the local segment without the need of WINS or NetBIOS since neither of these two systems
support IPv6. Furthermore, the introduction of a read-only domain controllers role in
Windows Server 2008 has resulted in the creation of primary read-only DNS zones in the
Windows DNS server system.
BitLocker provides an extra layer of security that can help keep your server secure. It
does add a bit of complexity, especially when you are performing updates on the system
that could alter any of the boot-related components; on the upside, it can prevent unauthorized
access through physical access. If you have a server in a remote location where
physical security cannot be guaranteed, the BitLocker solution gives you extra peace of
mind. As much as possible, take advantage of multi-factor authentication, such as TPM
plus PIN, so that in the unlikely event of a maliciously altered TPM, the PIN adds a secondary
line of defense for the system.
