Computer Systems Servicing NC II

  • Author: Kent Eric M. Narra

Server & Client

  • Focus on various elements including Server Configuration, Peer-to-Peer connections, Active Directory Services, Domain Name Services, and DHCP.

Server Configuration

  • Key components:

    • Peer to peer connection

    • Active Directory Services

    • Domain Name Services

    • Dynamic Host Configuration Protocol

    • Joining Client to the Domain

Peer to Peer Connection

  • Definition: A network model where computers (peers) communicate directly, sharing resources without a centralized server.

  • Benefits: Decentralized allowing devices to function as both clients and servers.

How P2P Networks Work

  • Each connected device has equal privileges.

  • Communication occurs directly between devices for file sharing, task processing, and workload distribution.

  • Types:

    • Pure P2P Network: No central server.

Active Directory Services (ADS)

  • Definition: A Microsoft-developed directory service for managing users, computers, and resources within a network.

  • Functions: Provides authentication, authorization, and directory management, centralizing network administration.

Components of Active Directory

  • Domain Controller (DC): Authenticates users and enforces security policies.

  • Active Directory Database (NTDS.dit): Repository for directory objects.

  • Organizational Units (OUs): Subdivisions for easier management.

  • Forest: Highest AD level with multiple domains.

  • Domain: Group of network objects managed under a single database.

  • Tree: Collection of related domains.

  • Global Catalog: Supports object searches across multiple domains.

Domain Name Services (DNS)

  • Purpose: Translates domain names into IP addresses, assisting in locating and connecting to internet services.

Dynamic Host Configuration Protocol (DHCP)

  • Function: Automatically assigns IP addresses and network configurations, eliminating manual setup.

Static IP Addressing

  • Definition: A fixed IP address set manually, contrasting DHCP’s automatic assignment.

Joining a Client to the Domain

  • Purpose: Allows centralized management through Active Directory, enabling policy enforcement and user account management.

User Accounts in Servers and Folder Redirection

  • User Account Definition: Unique identity for resource access, managed through directory services.

Types of User Accounts

  • Local User Accounts: Specific to a server, not centrally managed.

  • Domain User Accounts: Centrally managed allowing access from any network device.

  • Administrator Accounts: Elevated privileges for managing the server.

  • Guest Accounts: Temporary with restricted access.

Authentication and Permissions

  • Authentication: Verifying identities.

  • Authorization: Assigning access permissions.

  • Group Policies: Manage security and access control settings.

Folder Redirection in Servers

  • Definition: Allows users' folders to be stored on a network rather than locally.

Benefits of Folder Redirection

  • Centralized storage and backups.

  • Reduced login times due to smaller profile sizes.

  • Enhanced collaboration.

How Folder Redirection Works

  1. Admin enables via Group Policy Objects in Active Directory.

  2. Common folders redirected: Desktop, Documents, Downloads, Pictures.

  3. Files redirected to server locations.

  4. Offline access available; changes sync when online.

Configuring Folder Redirection (Steps)

  • Use Group Policy Management Console.

  • Navigate to User Configuration > Policies > Windows Settings > Folder Redirection.

  • Specify network paths and apply settings.

Troubleshooting Folder Redirection Issues

  • Common Issues: Permission errors, slow login, sync issues, GPO not applying.

  • Solutions: Check permissions, profile sizes, and group policies.

Remote Desktop & Printer Server

Remote Desktop in Servers

  • Definition: Tool for remote connection to computers, useful for administration and IT support.

Benefits of Remote Desktop

  • Remote access, centralized control, secure connections.

Enabling Remote Desktop on a Server

  • Steps to enable Remote Desktop and configure firewall settings.

Allowing Users to Connect

  • Manage user access through System Properties.

Using Group Policy for RDP Management

  • Configure session timeouts and security settings.

Secure Remote Desktop Best Practices

  • Utilize NLA, change default ports, implement 2FA, and restrict access.

Printer Server & Deployment

Benefits of a Print Server

  • Centralized management and control, reduced network load, easy troubleshooting.

Setting Up a Print Server on Windows Server

  1. Install Print Server Role.

  2. Add a printer and install drivers.

  3. Share printer on the network.

Deploying Printers via Group Policy

  • Automate printer deployment settings.

Verifying Printer Deployment

  • Check visibility for users.

Troubleshooting Printer Server Issues

  • Address common issues such as visibility and permission errors.

Conclusion

  • Overview provided the foundational understanding of servicing computer systems focusing on server and client architectures and management.
