Microsoft’s Active Directory (AD) offers IT system administrators a central way to manage user accounts and devices in an IT infrastructure network. Active Directory authenticates and authorizes users when they log onto devices and into applications, and allows them to use the settings and files across all devices in the network. Active Directory services are involved in multiple aspects of networking environments and enable interplay with other directories. Considering the important role AD plays in user data-management and security, it’s important to deploy it properly and consistently follow best practices.

Active Directory Basics is a tutorial that will help you address many AD management challenges. You’ll learn what really goes on under the Active Directory hood, including its integration with network services and the features that enable its many great benefits. This white paper also explains how administrators can make changes in AD to provide consistency across an environment.

In addition, the Active Directory Basics tutorial explains how to:

  • Log onto devices and into applications with the same username and password combination (other optional authentication methods)
  • Use settings and files across all devices, which are AD members
  • Remain productive on secondary AD-managed devices if the primary device is lost, defective or stolen.
  • Best practices to follow, and references for further reading
Understanding Windows Server Hyper-V Cluster Configuration, Performance and Security
The Windows Server Hyper-V Clusters are definitely an important option when trying to implement High Availability to critical workloads of a business. Guidelines on how to get started with things like deployment, network configurations to some of the industries best practices on performance, security, and storage management are something that any IT admin would not want to miss. Get started with reading this white paper that discusses the same through scenarios on a production field and helps yo
How do you increase the uptime of your critical workloads? How do you start setting up a Hyper-V Cluster in your organization? What are the Hyper-V design and networking configuration best practices? These are some of the questions you may have when you have large environments with many Hyper-V deployments. It is very essential for IT administrators to build disaster-ready Hyper-V Clusters rather than thinking about troubleshooting them in their production workloads. This whitepaper will help you in deploying a Hyper-V Cluster in your infrastructure by providing step-by-step configuration and consideration guides focussing on optimizing the performance and security of your setup.
vSphere Troubleshooting Guide
Troubleshooting complex virtualization technology is something all VMware users will have to face at some point. It requires an understanding of how various components fit together and finding a place to start is not easy. Thankfully, VMware vExpert Ryan Birk is here to help with this eBook preparing you for any problems you may encounter along the way.

This eBook explains how to identify problems with vSphere and how to solve them. Before we begin, we need to start off with an introduction to a few things that will make life easier. We’ll start with a troubleshooting methodology and how to gather logs. After that, we’ll break this eBook into the following sections: Installation, Virtual Machines, Networking, Storage, vCenter/ESXi and Clustering.

ESXi and vSphere problems arise from many different places, but they generally fall into one of these categories: Hardware issues, Resource contention, Network attacks, Software bugs, and Configuration problems.

A typical troubleshooting process contains several tasks: 1. Define the problem and gather information. 2. Identify what is causing the problem. 3. Fix the problem, implement a fix.

One of the first things you should try to do when experiencing a problem with a host, is try to reproduce the issue. If you can find a way to reproduce it, you have a great way to validate that the issue is resolved when you do fix it. It can be helpful as well to take a benchmark of your systems before they are implemented into a production environment. If you know HOW they should be running, it’s easier to pinpoint a problem.

You should decide if it’s best to work from a “Top Down” or “Bottom Up” approach to determine the root cause. Guest OS Level issues typically cause a large amount of problems. Let’s face it, some of the applications we use are not perfect. They get the job done but they utilize a lot of memory doing it.

In terms of virtual machine level issues, is it possible that you could have a limit or share value that’s misconfigured? At the ESXi Host Level, you could need additional resources. It’s hard to believe sometimes, but you might need another host to help with load!

Once you have identified the root cause, you should assess the impact of the problem on your day to day operations. When and what type of fix should you implement? A short-term one or a long-term solution? Assess the impact of your solution on daily operations. Short-term solution: Implement a quick workaround. Long-term solution: Reconfiguration of a virtual machine or host.

Now that the basics have been covered, download the eBook to discover how to put this theory into practice!

Why Network Verification Requires a Mathematical Model
Learn how verification can be used in key IT processes and workflows, why a mathematical model is required and how it works; as well as example use cases from the Forward Enterprise platform.
Network verification is a rapidly emerging technology that is a key part of Intent Based Networking (IBN). Verification can help avoid outages, facilitate compliance processes and accelerate change windows. Full-feature verification solutions require an underlying mathematical model of network behavior to analyze and reason about policy objectives and network designs. A mathematical model, as opposed to monitoring or testing live traffic, can perform exhaustive and definitive analysis of network implementations and behavior, including proving network isolation or security rules.

In this paper, we will describe how verification can be used in key IT processes and workflows, why a mathematical model is required and how it works, as well as example use cases from the Forward Enterprise platform. This will also clarify what requirements a mathematical model must meet and how to evaluate alternative products.
ESG Report: Verifying Network Intent with Forward Enterprise
This ESG Technical Review documents hands-on validation of Forward Enterprise, a solution developed by Forward Networks to help organizations save time and resources when verifying that their IT networks can deliver application traffic consistently in line with network and security policies. The review examines how Forward Enterprise can reduce network downtime, ensure compliance with policies, and minimize adverse impact of configuration changes on network behavior.
ESG research recently uncovered that 66% of organizations view their IT environments as more or significantly more complex than they were two years ago. The complexity will most likely increase, since 46% of organizations anticipate their network infrastructure spending to exceed that of 2018 as they upgrade and expand their networks.

Large enterprise and service provider networks consist of multiple device types—routers, switches, firewalls, and load balancers—with proprietary operating systems (OS) and different configuration rules. As organizations support more applications and users, their networks will grow and become more complex, making it more difficult to verify and manage correctly implemented policies across the entire network. Organizations have also begun to integrate public cloud services with their on-premises networks, adding further network complexity to manage end-to-end policies.

With increasing network complexity, organizations cannot easily confirm that their networks are operating as intended when they implement network and security policies. Moreover, when considering a fix to a service-impact issue or a network update, determining how it may impact other applications negatively or introduce service-affecting issues becomes difficult. To assess adherence to policies or the impact of any network change, organizations have typically relied on disparate tools and material—network topology diagrams, device inventories, vendor-dependent management systems, command line (CLI) commands, and utilities such as “ping” and “traceroute.” The combination of these tools cannot provide a reliable and holistic assessment of network behavior efficiently.

Organizations need a vendor-agnostic solution that enables network operations to automate the verification of network implementations against intended policies and requirements, regardless of the number and types of devices, operating systems, traffic rules, and policies that exist. The solution must represent the topology of the entire network or subsets of devices (e.g., in a region) quickly and efficiently. It should verify network implementations from prior points in time, as well as proposed network changes prior to implementation. Finally, the solution must also enable organizations to quickly detect issues that affect application delivery or violate compliance requirements.
Forward Networks ROI Case Study
See how a large financial services business uses Forward Enterprise to achieve significant ROI with process improvements in trouble ticket resolution, audit-related fixes and change windows.
Because Forward Enterprise automates the intelligent analysis of network designs, configurations and state, we provide an immediate and verifiable return on investment (ROI) in terms of accelerating key IT processes and reducing manhours of highly skilled engineers in troubleshooting and testing the network.

In this paper, we will quantify the ROI of a large financial services firm and document the process improvements that led to IT cost savings and a more agile network. In this analysis, we will look at process improvements in trouble ticket resolution, audit-related fixes and acceleration of network updates and change windows. We will explore each of these areas in more detail, along with the input assumptions for the calculations, but for this financial services customer, the following benefits were achieved, resulting in an annualized net savings of over $3.5 million.
