Active directory server 2019

Introduction

One of the best features that make Windows server to shine in the Enterprise sphere is Active Directory. This single Sign-on product that seamlessly and easily integrates with most of Microsoft products makes user management among other tasks quite easy and fun. This guide is about how to install Active Directory Domain Services on a newly installed Windows server 2019.

Adding the Active Directory Domain Services Role

But at first, you should set a static IP address on your server, and find the appropriate name for your Windows Server to match your company's naming policy. After completing this step, proceed to set up ADDS.

Run Server Manager, click Manage -> Add Roles and Features.

Right after that the wizard window appears. Under "Before You Begin" click "Next".

Now we need to select an installation type, it can be based on server roles or virtual infrastructure (based on Hyper-V), chose the first setting and continue in a new window.

In the "Server selection", we need to choose our server, usually it is allocated by default and continue to the next section.

Here we came to Server Roles, select Active Directory Domain Services and accept addition of related features. Click the Add Features -> Next.

The next window is named "Features" but here we need nothing to add so just go to the next section.

The ADDS section displays summary info about your AD, here we just click Next.

And at last, we proceed to installation, click Install and wait a little bit until installation completes.

Upgrading Server to a DC

After finishing the installation, unless you close the window, there will be a link in finish summary to promote the server to a DC. This is highlighted as blue text.

However, it is possible to promote the server through notifications in server manager.

Click on "Promote server to domain controller". And you will be brought to AD deployment wizard that will help you to create a forest in AD.

In "Deployment Configuration", you should choose the "Add a new forest", and then you need to think about your domain name (Note that it must not be like a domain name on your organization's website, it must differ, otherwise you will have serious DNS problems) and type it in the proper field. In my case it is office.local, and click Next afterwards.

Now we have reached the"Domain Controller Options". Here you need to specify the domain functional level. Note that it can differ from you current OS version, for 2019 Windows server, 2016 is only available. For the first AD server chose the latest version of the functional level. And if it is not the first one then you need to sync the level among other controllers.

In our example we will also choose DNS server option because we dont have standalone DNS, chose it whether you need it or not in your infrastructure.

You should also specify the password for restore mode (DSRM), save it in your corporate password

manager and click "Next" to continue.

Probably you will notice a DNS warning message, but it should not bother you at this time. Ignore it and move further.

So, we arrived to the NetBIOS name, I recommend you to leave it as it is but you can change it as you like, don’t forget to specify it in capital letters. Move Next.

Under "Paths" choose where the location of NTDS, SYSVOL and LOG folders. You can choose a different drive depending on your preferences and settings but default is also acceptable.

Under "Review Options" you will see a summary of your selections. Check it carefully for mistakes, move next if it is ok.

The "Prerequisites Check" section checks for your server prerequisites. Here, if it finds an error the installation process will be aborted and you will need to correct it. Otherwise, if only warning messages are displayed (which is usual), but the check was successful as shown, click Install to continue.

And here you need to wait a little bit for installation process to complete. Immediately after that, the server automatically restarts.

After server finishes its reboot process, your first domain controller will be ready to use and you can leverage all the features such as ADUC and ADAC.

Conclusion

You have Active Directory Domain Services Installed and can be managed by Active Directory Administrative Center. We hope it was informative and you enjoyed. Thank you for reading through. Other guides of interest are listed below:

Crontab in linux- Examples and Command

A cron job in Linux is a time-based job scheduler. It is a utility that allows you to schedule and automate the execution of scripts, commands, or programs at specific intervals or at predetermined times. Cron jobs are commonly used in Linux and other Unix-like operating systems to automate repetitive tasks, such as system maintenance, log rotation, backups, and periodic data processing. The cron service is responsible for running these scheduled tasks. It reads a configuration file called the "crontab" (short for cron table) to determine when and which commands to execute. Each user on a Linux system can have their own crontab file, which lists the cron jobs specific to that user The crontab file uses a specific format to define the schedule of a cron job. It consists of six fields that specify the timing of the job: scss * * * * * command_to_be_executed | | | | | | | | | +----- Day of the Week ( 0 - 7 ) (Sunday = 0 or 7 ) | | | +------- Month ( 1 - 12 ) | | +--

How TO Manage Groups Ad User on linux

Linux Admin - User Managemen When discussing user management, we have three important terms to understand − Users Groups Permissions We have already discussed in-depth permissions as applied to files and folders. In this chapter, let's discuss about users and groups. CentOS Users In CentOS, there are two types accounts – System accounts − Used for a daemon or other piece of software . Interactive accounts − Usually assigned to a user for accessing system resources . The main difference between the two user types is − System accounts are used by daemons to access files and directories. These will usually be disallowed from interactive login via shell or physical console login .. Interactive accounts are used by end-users to access computing resources from either a shell or physical console login. With this basic understanding of users, let's now create a new user for Bob Jones in the Accounting Department. A new user is added with the adduser command. Following

User quota in Linux step by step

Linux Admin – Quota Management As a Linux administrator, quota management is an important aspect of managing file systems and controlling disk usage by users. Quotas allow you to set limits on the amount of disk space a user or a group can consume. Here's a general guide on how to manage quotas in Linux: Enabling Quota Management in C Linux is basically a 4 step process – Step 1 − Enable quota management for groups and users in /etc/fstab. Step 2 − Remount the filesystem. Step 3 − Create Quota database and generate disk usage table. Step 4 − Assign quota policies. Enable Quota Management in /etc/fstab First, we want to backup our /etc/fstab filen − [root@localhost ~]# cp -r /etc/fstab ./ We now have a copy of our known working /etc/fstab in the current working directory. We made the following changes in the options section of /etc/fstab for the volume or Label to where quotas are to be applied for users and groups. usrquota grpquota As you can see, we

Why use vSAN in VMware?

VMware vSAN, which stands for VMware Virtual SAN, is a software-defined storage solution offered by VMware. It is a component of VMware's vSphere virtualization platform and is designed to provide highly scalable, high-performance shared storage for virtual machines (VMs) in a vSphere environment. vSAN allows you to pool together the direct-attached storage devices (such as hard drives or solid-state drives) from multiple servers in a vSphere cluster and create a distributed storage infrastructure. By aggregating the storage resources from these servers, vSAN creates a shared storage pool that can be utilized by VMs running on those servers. Key features and benefits of VMware vSAN include: Hyperconverged Infrastructure (HCI): vSAN is a key component of VMware's HCI solution. It combines compute, storage, and virtualization resources into a single software-defined platform, simplifying data center operations and reducing hardware costs.

What is? Dhcp Server In-Networking

A DHCP (Dynamic Host Configuration Protocol) server is a network service that automatically assigns IP addresses and other related network configuration parameters to devices on a network. It simplifies the process of network configuration by dynamically allocating IP addresses to devices as they connect to the network. PLAN the IP Address Range and Exclusions Besides degerming how to places the DHCP server into the network structure, you also to plan the ip address ranges you" ii use as well as which ip addresses to reserve or exclude from this pool of addresses. use the following list to help plan the IP address ranges to use and exclude . . Determine the range of ip addresses that the DHCP server will manage. Most likely, this will be private address range such as 10.x.x.x or 192.168.x.x, or a site-local addresses such as FEC::/10. .Make a list of any IP addresses to exclude to support hosts with static IP addresses. only DHCP server and hosts that don't' works as
