Using Directory Services Restore mode 2008-12-25 04:11:00 Active Directory
is a special kind of hierarchical database that stores system settings, computer information, user information, application configuration, and a wealth of other information and statistics about your network. In fact, Active Directory is the most important database on your server when this database becomes corrupted, it can prevent your server from booting because Windows can’t f Read more:Restore

Using the last known good configuration 2008-12-24 04:23:00 Many errors occur due to a configuration change. For example, you might install a new device driver and find that the system suddenly doesn’t boot because of it. A new application can cause the system to fail as well. Any change that affects the boot sequence can cause problems that seem impossible to fix. The Last Known Good Configuration (Advanced) option lets you use the configuration from th
Enabling boot logging in Windows Server 2008 2008-12-23 07:29:00 Whenever you start your computer in Safe Mode, you’ll notice a number of messages scrolling by that tell you which file Windows
is loading. Unfortunately, the list can scroll by so fast that you can’t read it. Knowing which file Windows is loading is important because loading the wrong file at the wrong time can prove fatal when getting the operating system to work. Selecting the Enable Boot L Read more:logging

Working with the Safe Mode options in Windows Server 2008 2008-12-22 04:41:00 Safe Mode is one of the oldest diagnostic features of Windows
, and it’s still one that you find used quite often to locate problems. The idea behind Safe Mode is that the operating system boots with the minimal number of features in place that are necessary for the operating system to work. By removing all the extraneous features, you can determine whether the operating system will even boot. If Read more:Windows Server
PKCS Standards 2008-12-20 10:05:00 Here is a list of active PKCS standards. You will notice that there are gaps in the numbered sequence of these standards, and that is due to the retiring of standards over time since they were first introduced.PKCS #1: RSA Cryptography Standard Outlines the encryption of data using the RSA algorithm. The purpose of the RSA Cryptography Standard is in the development of digital signatures and digit Read more:Standards
How PKI Works 2008-12-19 07:07:00 Perhaps helpful to understand the term encryption and how PKI has evolved. The history of general cryptography almost certainly dates back to almost 2000 B.C. when Roman and Greek statesmen used simple alphabet-shifting algorithms to keep government communication private. Through time and civilizations, ciphering text played an important role in wars and politics. As modern times provided new comm Read more:Works
PKI Enhancements in Windows Server 2008 2008-12-19 05:58:00 Windows Server 2008 introduces many new enhancements that allow for a more easily implemented PKI solution and, believe it or not, the development of such solutions. Some of these improvements extend to the clients, such as the Windows Vista operating system. Overall, these improvements have increased the manageability throughout Windows PKI. For example, the revocations services have been redesig Read more:Enhancements

Components of PKI 2008-12-18 05:13:00 In today’s network environments, key pairs are used in a variety of different functions.This series will likely cover topics such as virtual private networks (VPNs), digital signatures, access control (SSH), secure e-mail (PGP—mentioned already—and S/MIME), and secure Web access (Secure Sockets Layer, or SSL). Although these technologies are varied in purpose and use, each includes an implem Read more:Components
What Is PKI? 2008-12-17 04:45:00 The rapid growth of Internet use has given rise to new security concerns. Any company that does not configure a strong security infrastructure is literally putting the company at risk. An unscrupulous person could, if security were lax, steal information or modify business information in a way that could result in major financial disaster. To protect the organization’s information, the middleman
What NAP Does 2008-12-16 04:29:00 If you want a short definition of NAP, it’s this: NAP is a platform that can enforce compliance by computing devices with predetermined health requirements before these devices are allowed to access or communicate on a network. By itself, NAP is not designed to protect your network and is not intended to replace firewalls, AV products, patch management systems, and other protection elements. Ins
Understanding Network Access Protection 2008-12-15 08:08:00 There are already solutions around that can do some of these things. Some of them are homegrown. For example, one organization I’m familiar with uses a DHCP registration system that links MAC addresses to user accounts stored in Active Directory to control which machines have access to the network. But homegrown solutions like this tend to be hard to manage and difficult to maintain, and they ca Read more:Access

Planning for IPv6 Transition Technologies 2008-12-13 21:00:00 You will need to use one or more IPv6 transition technologies during the IPv6 migration process. The below provide planning information for ISATAP, 6to4, and Teredo.ISATAPBy default, ISATAP hosts will obtain the IPv4 address of the ISATAP router by using DNS and other IP name resolution techniques to resolve the name ISATAP to an IPv4 address. Once the host has identified the ISATAP router’s IP
Migrating to IPv6 2008-12-13 07:55:00 Upgrading to an exclusively IPv6 environment should be a long-term goal. You will need to follow these general steps (with proper testing prior to any implementation) to migrate to IPv6:1. As you deploy new computers or operating systems, configure them to support both IPv6 and IPv4. If you plan to continue using computers running Windows XP and Windows Server 2003, gradually enable IPv6 across yo Read more:Migrating
Advancing Microsoft’s Strategy for Virtualization 2008-12-12 06:03:00 Microsoft is leading the effort to improve system functionality, making it more self-managing and dynamic. Microsoft’s main goal with virtualization is to provide administrators more control of their IT systems with the release of Windows Server 2008 and Hyper-V. This includes a faster response time to restore that is head and shoulders above their competition. Windows Server 2008 provides a tot Read more:Microsoft

DHCP Messages 2008-12-10 17:56:00 DHCP clients and DHCP servers communicate by exchanging DHCP messages. There are eight types of DHCP messages, all of which are sent as User Datagram Protocol (UDP) messages. DHCP clients in the process of obtaining an IP address configuration use broadcast DHCP messages, sent to the limited broadcast IP address 255.255.255.255. DHCP clients with an IP address and a valid lease use unicast DHCP me
The Disadvantages of IPv4 2008-12-09 08:09:00 On today’s Internet, IPv4 has the following disadvantages:• Limited address space. The most visible and urgent problem with using IPv4 on the modern Internet is the rapid depletion of public addresses. Due to the initial address class allocation practices of the early Internet, public IPv4 addresses are becoming scarce. Organizations in the United States hold most public IPv4 address space wor
User Datagram Protocol (UDP) 2008-12-07 09:01:00 UDP, defined in RFC 768, has the following characteristics:• Connectionless Nodes send UDP messages, consisting of a UDP header and a message, without having to negotiate a connection between communicating peers.• Unreliable Nodes send UDP messages as datagrams without sequencing or acknowledgment. The Application Layer protocol must reorder and recover lost messages. Typical UDP-based Applica Read more:Protocol
Configuring Domain Name System (DNS) 2008-12-04 18:31:00 Microsoft defines the Domain Name System
(DNS) as a hierarchical distributed database that contains mappings of fully qualified domain names (FQDNs) to IP addresses. DNS enables finding the locations of computers and services through user-friendly names and also enables the discovery of other types of records used for additional resources in the DNS database.A much broader definition comes from th Read more:Configuring
Adding the Terminal Server Role 2008-12-02 18:00:00 You can use the Server Manager, as with other roles in Windows Server 2008, to install Terminal Services. When you use Server Manager to install Terminal Services, you can choose from five options:Terminal ServerThis installs the core of TS functionality, including the ability to just share one application with TS RemoteApp.TS LicensingDeploys a TS Licensing Server to manage client access licenses
The Remote Desktop Protocol 2008-12-01 17:57:00 The RemoteDesktopProtocol
(RDP) is the protocol that drives Terminal Services. RDP is based on and is an extension of the T.120 protocol family of standards. It is a multichannel-capable protocol that allows for separate virtual channels for carrying device communication and presentation data from the server, as well as encrypted client mouse and keyboard data. RDP provides a very extensible bas
Core Enhancements to Terminal Services 2008-11-24 18:00:00 Windows Server 2008 has a number of core improvements in how Terminal Service works. Most of the improvements we’ll look at were first introduced in Windows Vista, but for some of these enhancements to work in Windows Vista you need Windows Server 2008 running on the back end as your terminal server. Many of these improvements center around changes to the Remote Desktop Connection client that co Read more:Enhancements

Terminal Services RemoteApp 2008-11-19 17:45:00 One of the biggest improvements and enhancements of Terminal Services
in Windows Server 2008 is in the area of experience features, Terminal Services RemoteApp, which enables users to access standard Windows-based programs from anywhere by running them on a terminal server instead of directly on their client computers. In previous versions of Terminal Services, you could remote only the entire des
TS Gateway, ISA Server, and NAP Working Better Together 2008-11-14 21:36:00 Terminal Services–based remote access has long been used as a simpler, lower-risk alternative to classical layer 2 VPN technologies. Whereas the layer 2 VPN has often provided “all ports, all protocols” access to an organization’s internal network, the Terminal Services approach restricts connectivity to a single well-defined port and protocol. However, as more and more capability has asce Read more:Gateway
