Study Notes

Server 2019 Versions

Server 2019 versions can be installed without the desktop experience.
Essentials: Up to 25 users, lower price
Standard: 2 Hyper-V VMs
Datacenter: unlimited VMs, very expensive

Upgrading/Downgrading

Server 2012 R2 and 2016 can be upgraded to 2019.
Downgrade is only possible to Server 2016.
Downgrades require permission from Microsoft.
Backups are required for both upgrades and downgrades.

BitLocker/EFS

All Server 2019 versions support BitLocker; enable it in PowerShell or Server Manager.
BitLocker encrypts entire volumes.
BitLocker encryption is volume-based, not file-based.
When BitLocker is used for files, they become extremely small volumes.
Only authorized users can access data encrypted with BitLocker.
EFS is a feature introduced in version 3.0 of NTFS that provides file system-level encryption.

Boot/Install.wim

Default boot and .wim images are available on the DVD.

Windows Image File (boot.wim)

This image file is used to boot the operating system.
It contains Windows PE (Pre-installation Environment).
WDS (Windows Deployment Services) sends the boot file to target computers first.
The target computer uses this image to boot into Windows PE and then choose additional options.

WDS Terminology

A Standard Image is created in WDS to deploy images from reference computers.
A Discover Image is used when PXE compliant network cards are not available.

DNS Records

The DNS zone for AD DS is a forward lookup zone.
AD DS domains require a corresponding DNS zone (e.g., contoso.com).

AD CS (Certificate Services)

Standalone certificate servers (root authority) are often kept offline.
Subordinate certificate servers only trust root CAs.
Certificates can be invoked or revoked.

SCCM

System Center Configuration Manager deploys software based on schedules.
Administrators can deploy applications and get reports on success/failure.
Requires purchasing license.

File Server Resource Manager (FSRM)

Manages storage quotas and usage for storage users.
Sets quotas on folders; creates reports monitoring storage usage.
Includes quota management, file screening, classification, and storage reporting management functionalities.

Print Spooler

Manages print jobs sent to a computer printer or print server.
It's recommended to separate it from the C drive for better performance with high volume of users.
Used to manage print jobs awaiting printing, allows deletion or other actions.

RAID

RAID (Redundant Array of Inexpensive Disks) can confirm RAID properties in Disk Management.
RAID types: 0 (Striping), 1 (Mirroring), 5 (Parity bit), 10 (1+0; combination of 1 and 0).

Remote Desktop Services (RDS)

Allows remote users to access network resources and local drives via a remote connection.

NTFS Data Compression

NTFS data compression is used in the file system.
Tools like WinZip compress files into archives.
Files must be decompressed before use.

Automating Tasks

PowerShell has cmdlets and scripts for automating tasks.
Executables can also be used as standalone tools.
Install-WindowsFeature and servermanagercmd.exe are tools to add roles to a server.

DHCP Process

DHCP discovers available DHCP servers.
DHCP servers respond with IP addresses to clients.
Clients make requests to servers for dynamic IP addresses.

DHCP Leases

Default lease length in Windows Server is 8 days.
Clients attempt to renew leases with the original server (50% = 4 days, 87.5% = 7 days).
IP addresses are lost if leases cannot be renewed.
Routers block broadcast packets between networks.
DHCP relay is needed to service multiple subnets from a single server

WSUS

Automatically synchronizes with Microsoft Update.
Approves updates to be deployed in the environment.
Keeps track of updates and detailed status reports on each system.

ADREPLSTATUS

Tool for analyzing Active Directory replication status.

Performance Monitor (Perfmon)

Monitors and creates graphs and data sets to gather network and other performance data.
Custom data collector sets can be created to monitor and troubleshoot issues

Offline Files

Allows users to connect to and download files to their PCs when not connected to a central folder.
Offline files are used in shared folders—only specified files are cached.
Enabled through group policy.

DFS (Distributed File System)

Replicates files to various locations across a network.
Enables file sharing between multiple Windows servers.

Folder Redirection

Forwards user home directories to central locations.

ISS (Internet Information Services)

Manages websites and web applications.

GPO Backup

GPO can be backed up in GPMC.
After choosing to back up, the location is specified.

Active Directory Tombstone

When objects in Active Directory are deleted, they go to the recycle bin for a specific amount of time (180 days).
