What is Windows Deployment Services (WDS)? How to setup and use WDS?  Windows Deployment Services (WDS) is a network-based installation tool from Microsoft for deploying Windows operating systems. It's primarily used to automate the installation of Windows across large numbers of computers, reducing the time and effort required to install the operating system manually. Here are the full steps to set up and use WDS: Prerequisites Active Directory: The server running WDS needs to be a member of an Active Directory domain. DHCP: Ensure a DHCP server is available for client computers to receive IP addresses. DNS : Domain Name System service is required for WDS. NTFS Partition : The WDS server must have an NTFS file system on the image store partition. Setting Up Windows Deployment Services 1. Install WDS Role Open Server Manager. Click on "Add roles and features". Select "Role-based or feature-based installation". Choose your server from the server pool. In the Se...

Network Load Balancing:                    Youtube Link:   In short, NLB stands for Network Load Balancer. It is a type of load balancer that operates at the transport layer (Layer 4 - TCP/IP) in the OSI ( Open Systems Interconnection) model and is used to distribute network traffic across multiple servers to optimize resource use (Web server) , maximize throughput, reduce latency, and ensure high availability and reliability of applications or services. Network Load Balancers are particularly effective for managing large volumes of traffic and are capable of handling millions of requests per second. Network Load Balancers (NLB) offer several benefits that are crucial for optimizing the performance and reliability of networked applications and services. Here are some key advantages: High Availability and Reliability : NLBs distribute incoming traffic across multiple servers, ensuring that if one server fails, others can handle the ...

AD User Profiles:    AD User Profiles An AD (Active Directory) User Profile is a collection of user-specific settings and data that are stored centrally on a network server. This allows users to maintain their personalized settings, such as desktop layout, color schemes, and application preferences, across multiple computers.  Types of User Profiles:  1. Local Profile:    User profile stored locally on the device. Changes made to the profile are only applied to that specific device. Simplest type of profile, but lacks synchronization capabilities.   2. Roaming Profile:   User profile that is synchronized between devices. Allows users to maintain their personalized settings across different computers. Requires network connectivity for synchronization.  3. Mandatory Profile:  System-defined profile that cannot be modified by the user. Enforces a consistent user experience across all devices. Useful for standardized environments w...
