42. SNTP in Active Directory

• Simple Network Time Protocol
• Automatically synchronizes clocks on machines that are members of Active Directory domains
• Synchronization hierarchy can be defined
• All times in Windows Server 2003 are stored as Universal Coordinated Time (UTC) and adjusted in the GUI for the time zone
• Time synchronization is not vital for Active Directory replication (differs from other directory services), but is crucial for Kerberos authentication

41. DHCP in Active Directory 2003

• Dynamic Host Configuration Protocol
• Used to provide computers with IP addressing configuration, such as
• DNS server address(es)
• DNS domain suffix
• Disabling of NetBIOS (Windows 2000 or later)
• Release IP address on shutdown (Windows 2000 or later)
• IPv4 and IPv6 configuration
• Custom-defined options

40. TCP/IP in Active Directory 2003

• Transmission Control Protocol/Internet Protocol
• Internet standard protocol
• Interoperable
• Robust
• Versions 4 and 6 supported in Microsoft® Windows® Server 2003
• Inherent component of Windows Server 2003 functionality
• Active Directory technologies use TCP/IP for communication and connectivity

38. Difference between server 2003 and server 2008 (2003 vs 2008)

Server 2003 vs. Server 2008.

1.    We can install windows 2008 server either in full version(install all services& applications) or server core(only install minimal required services), but in 2003 we can only install fully O.S.
2.    Windows server 2008 use Hyper-V application & Roles concept for better productivity but server 2003 does not have such features.
3.    Windows 2008 is a combination of vista and server 2003 r2.
4.    Some new services introduced in windows server 2008 are
a.    Read only domain controller (RODC)
b.    Windows Deployment server (WDS) instead of RIS server 2003
c.    Shadow copy of each and every folder.
d.    Boot sequence is changed
e.    Installation is faster in 2008 why because installation is 32 bit where as in 2003 is 16 bit as well 32.
f.    Services are known as role in it.
g.    Group policy editor is a separate option in Ads
h.    Main difference is Virtualization server 2008 has virtualization management.
i.    2008 has more inbuilt components and updated third party drivers.
j.    Introduced a new feature called Hyper-V (V for virtualization) only in 64 bit versions.
k.    Server 2008 is designed with number of new power saving features.  It includes updated support for Advanced Configuration and Power Interface (ACPI) processor power management (PPM) features, including support for processor performance states (P-states) and processor idle sleep states on multiprocessor systems. These features simplify power management in Windows Server 2008 (WS08) and can be managed easily across servers and clients using Group Policies.
