Windows Server 2012 : IPv6 Introduction (part 4) - IPv6 Transition Technologies

Today, the Internet (and the world) is mostly running on IPv4 networks. As more and more operating system and devices natively support IPv6, and even require it, making IPv6 work globally will quickly become necessary.

Windows Server 2012 : IPv6 Introduction (part 3) - Comprehending IPv6 Addressing

Learning IPv6 notation can be a bit daunting at first, based not only on the use of hexadecimal numbering, but also on the length of a full address.

Windows Server 2012 : IPv6 Introduction (part 2) - IPv6 Addressing

With the expanded address space associated with IPv6, the developers of IPv6 decided to leverage the hexadecimal numbering system to simplify and reduce the number of characters to identify the IPv6 address.

Windows Server 2012 : IPv6 Introduction (part 1)

Network administrators had to work hard in some cases to support the quick growth and to troubleshoot issues because IPv4 required manual configuration of addressing on devices and in most cases they also had to deploy and support a method of dynamic addressing provided by, you guessed it, DHCP services

Windows Server 2012 : Exploring Advanced DHCP Concepts

The concepts advanced by DHCP include the functionality not used in daily situations, such as superscopes, ranges of multicast, and the delegation of the administration of DHCP. Moreover, in the environment of calculation of today, the management of the services by a command line environment is strongly desired. The following sections cover these advanced concepts of DHCP.

Windows Server 2012 : Managing Users and Data with Dynamic Access Control - Automatic File Classification

Windows Server 2012 : Deploying Dynamic Access Control (part 3) - Adding a Resource Property to the Global Resource Property List, Creating a New Central Access Rule

Every resource property has to be added to a resource property list. These lists make the resource property available to file servers. DAC resources can have individual lists target specific file servers, but for our purposes here, we are going to add the resource property to the Global Resource Property List.

Windows Server 2012 : Deploying Dynamic Access Control (part 2) - Configuring Resource Property for Files

To create a new resource property, from the ADAC click Resource Properties, New, and then Resource Property.

When configuring claim types for users, you are adding existing Active Directory attributes to the list of attributes used to evaluate who gets access to what.

Windows Server 2012 : Managing Users and Data with Dynamic Access Control - The Building Blocks of DAC , Requirements and Predeployment Pointers

Without question, the one major new capability that you will have to get to know at some time or another—and no matter how big or small the infrastructure—is Dynamic Access Control (DAC).

Windows Server 2012 Technology Primer : Improvements for Continuous Availability (part 2) - Hyper-V Replication

With Windows Server 2012, continuous availability now extends between sites; so, beyond local clustering and high availability, organizations can now do disaster recovery and business continuity with site-level guest session replication.

Windows Server 2012 Technology Primer : Improvements for Continuous Availability (part 1) - No Single Point of Failure in Clustering,Stretched Clusters, 64-Node Clusters

Although clustering of servers has been around for a long time in Windows (dating back to Windows NT 4.0, when it was available, but really didn’t work), clustering in Windows Server 2012 now not only works, but also provides a series of significant improvements.

Windows Server 2012 Technology Primer : Versions of Windows Server 2012

Microsoft has greatly simplified the licensing and version options for Windows Server 2012. There are effectively only two versions of Windows Server 2012 now: the Standard edition and the Datacenter edition.

Windows Server 2012 Technology Primer : When Is the Right Time to Migrate?

Every time a new version of Windows ships, organizations wonder when the right time to migrate to the new operating system. It used to be that you waited until the first service pack shipped before installing any Microsoft product.

Windows Server 2012 Technology Primer : Windows Server 2012 Defined - Windows Server 2012 as an Application Server

As much as there have been significant improvements in Windows Server 2012 under the hood that greatly enhance the performance, reliability, and scalability of Windows Server 2012 in the enterprise, Windows servers have always been exceptional application servers hosting critical business applications for organizations.

Windows Server 2012 Technology Primer : Windows Server 2012 Defined - Windows Server 2012 Under the Hood

Introduced in Windows Server 2012 is Server Message Block 3.0, more commonly called SMB3 or SMB for short. SMB is a protocol that handles the transfer of files between systems.

Windows Server 2012 : Scalable and elastic web platform (part 7) - Generating Windows PowerShell scripts using IIS Configuration Editor

To configure these settings, you need to drill down and edit configuration files like ApplicationHost.config, the root configuration file that includes detailed definitions of all sites, applications, virtual directories, and application pools on the server, as well as global defaults for all web server settings.

Windows Server 2012 : Scalable and elastic web platform (part 6) - FTP Logon Attempt Restrictions

Brute-force attacks can create a Denial-of-Service (DoS) condition that can prevent legitimate users from accessing an FTP server. To prevent this from happening, IIS 8 includes a new feature called FTP Logon Attempt Restrictions that lets you block offending users from logging on to an IIS FTP server for a specified period of time

Windows Server 2012 : Scalable and elastic web platform (part 5) - Application Initialization,Dynamic IP Address Restrictions

When a web server receives unwanted activity from malicious clients, it can prevent legitimate users from accessing websites hosted by the server. One way of dealing with such situations in previous versions of IIS was to use static IP filtering to block requests from specific clients.

Windows Server 2012 : Scalable and elastic web platform (part 4) - IIS CPU throttling

Managing CPU resources on farms of web servers in a multi-tenant shared hosting environment can be challenging. When you are hosting websites and applications from many different customers, each of them wants to get its fair share of resources.

Windows Server 2012 : Scalable and elastic web platform (part 3) - Centralized SSL certificate support

Cloud hosting providers that need to host multiple HTTPS websites on each server in their web farms can also benefit from other SSL-related improvements in IIS 8. These improvements help make the IIS platform more scalable and manageable for hosting secure websites.

Windows Server 2012 : Scalable and elastic web platform (part 2) - Server Name Indication

In previous versions of IIS, you could use host headers to support hosting multiple HTTP websites using only a single shared IP address. But if you wanted these websites to use Hypertext Transfer Protocol Secure (HTTPS), then you had a problem because you couldn’t use host headers.
