Read-Only Domain Controllers
Windows Server 2008 introduces a new type of domain controller (DC), the read-only domain
controller (RODC). This DC hosts read-only partitions of the Active Directory Domain Services (ADDS)
database. An RODC provides a secure solution for DC deployments to remote sites that require fast
and reliable authentication but do not necessarily have adequate physical security for the deployed
servers.

Networking requirements
TCP/IP
Microsoft has updated the TCP/IP stack in Windows Server 2008. For more information on the next
generation TCP/IP stack in Windows Server 2008, visit the Microsoft website:
www.microsoft.com/technet/community/columns/cableguy/cg0905.mspx.
NDIS 6.0
NDIS 6.0 is the next major version of the Network Driver Interface Specification. HP has updated the
Windows Server 2008-capable network adapter drivers to meet the NDIS 6.0 requirements. A list of
supported network adapters may be found in Table 5. For more information on NDIS 6.0, visit the
Microsoft website: http://msdn2.microsoft.com/en-us/library/ms795192.aspx.
IPv6
Windows Server 2008 provides support for the next generation TCP/IP protocol stack known as
Internet Protocol version 6 (IPv6). Administrators should be aware that IPv6 support is enabled by
default in a Windows Server 2008 installation. It cannot be uninstalled but may be disabled. For
more information on IPv6, visit the Microsoft website:

Windows Hardware Error Architecture (WHEA)
Windows Hardware Error Architecture is a new feature added to Windows Server 2008 that
provides a common infrastructure for hardware errors on Windows platforms.
The initial implementation of WHEA focuses on platform hardware devices, including processor,
memory, cache, and system interconnects such as PCI, PCI-X, and PCI Express. Peripheral device
errors remain under the control of their respective device drivers.
WHEA provides several benefits:
• A generic error source discovery mechanism
• A common hardware error record format and error handling flow
• A persistence mechanism for preserving error records
• A hardware error event tracking model based on Event Tracing for Windows (ETW)
Not all HP servers that support Windows Server 2008 will be WHEA compatible.

WHEA-capable ProLiant servers. HP has updated the following deliverables in support of WHEA:
• System ROMs for specific ProLiant server platforms planned for WHEA support (see

Table 2
• iLO firmware (version 1.42 or later)
• iLO 2 Management Controller Driver for Windows Server 2008 [hpqilo2.sys, Version 1.5 (or later)]
