Networking Concepts and Outlook Management

DHCP

• DHCP stands for Dynamic Host Configuration Protocol
• It automatically assigns IP addresses to devices on a network
• IP addresses allow devices to communicate with one another

DNS

• DNS stands for Domain Name System
• It translates domain names (like google.com) into IP addresses (like 172.217.160.142)
• IP addresses are what computers use to communicate

Accessing Files on a Network

• Use the network path to access files on a shared drive, e.g., \computer name\c$\
• This path directs the computer to the C drive of the specified computer on the network.

Outlook Profile

• Delete the existing Outlook profile by navigating to the Control Panel and selecting Mail.
• Select "Add" to create a new profile.
• Add a new account and follow the prompts to configure it.

Recovering Deleted Items

• Deleted items in Outlook are moved to the Deleted Items folder.
• You can access the folder and recover items from there.
• However, they are permanently deleted when the Deleted Items folder is emptied.

VHD Files

• VHD stands for Virtual Hard Disk
• It's a file that acts as a virtual hard drive, allowing you to create and run virtual machines.

Virtualization

• Virtualization creates a virtual version of a physical system, like a computer or server.
• Virtual machines (VMs) can run different operating systems and software on the same physical hardware
• This allows efficient resource utilization and better flexibility.

Granting Access to Mailboxes

• Go to the Office 365 admin center.
• Select the user whose mailbox you want to manage.
• Under Manage Sharing, choose Delegate access.
• Grant the delegate the desired permissions for access to the mailbox.

Retaining Ex-Employee Data

• In Office 365, you can retain data after removing a user's license.
• This ensures that emails and other data are retained according to company policy while the employee's account is no longer active.

Setting Up Online Archiving

• Go to the Office 365 admin center.
• Click on the “Compliance” section.
• Select “Data Governance” followed by “Archiving”.
• Set up the archiving policies for both user mailboxes and public folders.

Off boarding Employees

• Disable their access to company systems, including email and other applications.
• Disconnect them from all devices and collect company assets.
• Revoke access to company resources.
• Ensure that data is properly managed and retained according to company policy.

Blocking Spam Emails

• Configure spam filters for both the server and client-side email programs, including Outlook.
• Use blacklists to prevent email from known spam sources.
• Use whitelists to ensure that emails from trusted sources are not blocked.

Quarantined Emails

• If an email is in quarantine, it means the email system determined it may be spam or harmful.
• You can manually review the email and then release or permanently delete it.

Troubleshooting Network Printers

• Check the network printer's connection to the network, as well as the network connection on the computer.
• Ensure the printer is properly configured in the network settings.
• Confirm the users have the required permissions to print, as well as check printer queues for any stuck jobs.
• Restart both the printer and the affected devices.

Email Aliases

• Email aliases provide multiple addresses for a single mailbox.
• This allows you to receive emails at different addresses while the email is delivered to the same inbox.

Troubleshooting Missing Emails

• Check the Junk/Spam folder.
• Verify the recipient's email address is correct.
• Make sure the sender hasn’t blocked your email address.
• Check if there is internet connectivity.
• Ensure there are no email server outages or issues.

Prioritizing IT Issues

• Prioritize the whole company's email system being down as this affects the most users.
• A company director's inability to print should be the next priority because it impacts company leadership.
• The finance team's access to a folder is third, as it relates to essential business functions.
• A single user's password reset is the least important because it only affects one person.

Troubleshooting a Blue Screen

• Try updating the graphics card drivers.
• Run a memory test to check for any RAM issues.
• Run a hard drive test to check for any errors.
• Reset the PC to factory settings.

Troubleshooting Internet Outage

• Verify the internet connection is active, including router and modem.
• Check if other devices can connect to the internet.
• Contact your internet service provider for assistance.

Web Browsing Process

• Typing Google.com into the browser address bar sends a request to a DNS server.
• The DNS server translates google.com into an IP address, such as 172.217.160.142.
• The browser sends a request to the IP address, which hosts the Google website.
• The web server responds with the website's data (HTML, images, and scripts).
• The browser receives the data and displays the Google website.
