IT Officer Joins a Computer to the Domain

 To allow an IT officer to join client computers to the domain but restrict their ability to delete objects in Active Directory (AD), you can create a custom delegation in AD with specific permissions. Here’s how you can do it:

Step-by-Step Guide

1. Open Active Directory Users and Computers (ADUC)

   • Press Win + R, type dsa.msc, and press Enter.

2. Delegate Control to the IT Officer

   • In the ADUC console, right-click the Organizational Unit (OU) where you want to allow the IT officer to join computers to the domain (e.g., Computers or a specific OU).
   • Select "Delegate Control...".

3. Delegation of Control Wizard

   • Click "Next" on the Welcome screen.
   • Click "Add..." to add the user or group (e.g., the IT officer or a group of IT officers).
   • Enter the name of the user or group and click "OK", then "Next".

4. Choose Tasks to Delegate

   • Select "Create a custom task to delegate" and click "Next".
   • Choose "Only the following objects in the folder" and check "Computer objects".
   • Ensure "Create selected objects in this folder" is checked. Do not check "Delete selected objects in this folder".
   • Click "Next".

5. Specify Permissions

   • Check "Read", "Write", and "Reset Password".
   • Also, check the following specific permissions if they are listed:
     • Validated write to DNS host name
     • Validated write to service principal name
     • Write account restrictions
   • Click "Next" and then "Finish".

Verify the Permissions

1. Open Active Directory Users and Computers (ADUC)
   • Navigate to the OU where the delegation was set.
   • Right-click the OU and select "Properties".
   • Go to the "Security" tab and click "Advanced".
   • Look for the permissions assigned to the IT officer or group to ensure they are set correctly.

Adding a Computer to the Domain

1. IT Officer Joins a Computer to the Domain
   • The IT officer can now join computers to the domain by right-clicking This PC, selecting Properties, and then Change settings under Computer name, domain, and workgroup settings.
   • Click on Change, select Domain, and enter the domain name.
   • Provide credentials when prompted.

Prevent Deletion of Objects

Since the IT officer only has permissions to create and not delete computer objects, they will be unable to delete computers from the AD. The permissions granted are specific to creating and managing computer accounts without the ability to remove them.

Testing and Validation

1. Test the Permissions
   • Have the IT officer join a computer to the domain and verify that it appears in the specified OU.
   • Attempt to delete a computer object to ensure the deletion is not permitted.

By following these steps, you can ensure that the IT officer has the necessary permissions to join computers to the domain while preventing them from deleting any objects in Active Directory.

How to map network drives with Group Policy

 How to map network drives with Group Policy

How to map network drives with Group Policy

In earlier days, system administrators relied only on logon scripts to map networking drives, a complex and time-consuming process. To eradicate these hindrances, sysadmins rely on Group Policy to map network drives. In this article, we’ll learn why Group Policy is preferred and how you can map networking drives with GPO.

Why use Group Policy drive mapping

Using Group Policy to map network drives helps you to:

Avoid the hassle of scripting

Save time and effort by running scripts in the background

Accelerate the login process without having to reboot or restart the system

Improve scalability as it is robustly integrated with Active Directory

Enhance pliability while managing drive by using item-level targeting to apply preference settings to either group or individual user and computer

Steps to map a network drive using Group Policy on Windows Server 2012  R2

1. Open Group Policy Management in Active Directory

Open Server Manager > Tools > Group Policy Management.

or

Open Run command window > Type gpmc.msc > click Ok.

2. Create a new GPO to map the drive

Right-click on the OU in which you have created the user account, then click  Create a GPO in this domain and link it here…

In the New GPO window, enter a new name to identify the policy.

3. Modify the GPO settings

Right-click on the newly created GPO and choose Edit.

Click User configuration > Preferences > window settings > Right click on Drive Maps > New > Mapped Drives. 

    4. Configure drive properties

In the General tab, configure the settings below:

Choose one of the following options from the Action dropdown list box

Create: To create new mapped drive for the users.

Replace: To replace the existing mapped drive and if there is no drive in existence, it will create a new mapped drive.

Update: To modify the existing mapped drive’s configuration; if not, it creates a new mapped drive.

Delete: To delete a particular mapped drive for the user.

Location: Enter the path to the drive to be mapped.

Reconnect: Enable this check box to reconnect automatically irrespective of policy removal.

Drive letter: Assign a letter for the drive.

Label as: Assign a suitable name for the drive (e.g., SharedDrive).

Connect as: Use either current user account credentials or credentials of different accounts.

Hide/Show this drive: Choose whether you want to hide or show the mapped drive in windows explorer.

Hide/Show all drives: Choose whether you want to hide or show all the drives (mapped and physical) in windows explorer.

Click Apply and then, Ok to save the settings.

In the Common tab, configure these additional settings:

Choose Item-level targeting, and click Targeting.

In the Targeting Editor window, click New Item.

Choose Security Group among the items listed.

Click … and enter the name of the security group.

Click Ok to close the Targeting Editor window.

Click Apply and then Ok to close the Drive properties.

To check if the policy is applied, you can run gpupdate in command prompt, and as soon as the GPO is updated, you can find the mapped drive in File Explorer.

Mapping network drives with GPO for individual users

If you want to map network drive for individual users, you need to create a folder with your user’s logon name or sAMAccountName in the file server and then, follow the below steps:

In Group Policy management console, create a GPO and link it to domain.

Right-click on the newly created GPO > Edit.

In the Group Policy management editor,

Click User configuration > preferences > windows settings.  

Right-click on Drive maps > New > Mapped drives. 

In the new drive properties, choose an action ( e.g., Update) and enter a file server path with %UserName%, as the user’s logon name. Fill in the other fields, then click Apply and Ok. 

Observations and tips

Once Group Policy is applied, the mapped drive will show up almost immediately. If it does not appear, you need to do either of the following:

Ensure the policy is promptly applied to the appropriate user account. You can do that by running “gpupdate/r” on the command prompt.

Ensure the given drive letter is not already used. The drive actions depend on the letter assigned, wherein, if the letter is already being used, the create, and update actions cannot be performed, and actions such as delete and replace could be used.

Final thoughts

We have learned how to map network drives using GPO and found it to be one of the easiest and simplest methods of mapping, unlike the regular logon scripts which require scripting knowledge and experience. Also, the item-level targeting is helpful for focusing on individual users, enabling you to manage them efficiently.

Router Reset Process

 

Understanding the Router Reset Process

Before we dive into the nitty-gritty of resetting your router, it's important to understand the different types of resets and when to use them.

Soft Reset vs. Factory Reset

A soft reset involves simply turning your router off and on again. This can often resolve minor issues without changing any of your settings. A factory reset, on the other hand, erases all custom settings and returns the router to its original state.

When to Perform a Factory Reset

You might want to consider a factory reset if:

• You've forgotten your router's password
• You're experiencing persistent connectivity issues
• You're selling or giving away your router
• You suspect your router has been hacked

Precautions Before Resetting

Before you reset your router, make sure to:

• Write down your current WiFi name and password
• Note any custom settings you've applied
• Ensure you have your internet service provider's information handy

How to Reset WiFi Router: Step-by-Step Guide

Now that we've covered the basics, let's walk through the process of resetting your WiFi router.

Locating the Reset Button

The reset button is typically a small, recessed button on the back or bottom of your router. It's often labeled "Reset" or "RST".

Performing the Reset

1. Locate the reset button on your router
2. Use a paperclip or pin to press and hold the button for 10-15 seconds
3. Watch for the router's LED lights to change, indicating the reset process has begun
4. Release the button and wait for the router to restart (this usually takes 2-3 minutes)

During the reset process, you'll notice the LED lights on your router changing. This is normal and indicates that the reset is in progress.

Post-Reset Router Configuration

After resetting your router, you'll need to reconfigure it. Here's what to do:

Reconnecting to the Default Network

Look for a new WiFi network with the default name (usually printed on the router). Connect to this network using the default password.

Accessing Router Settings

Open a web browser and enter your router's IP address (often 192.168.0.1 or 192.168.1.1). Log in using the default username and password (usually "admin" for both).

Customizing Your Settings

Once logged in, you can:

• Change your WiFi name (SSID) and password
• Set up security settings (use WPA2 if available)
• Configure any other custom settings you need

Troubleshooting Common Reset Issues

Sometimes, things don't go as smoothly as we'd like. Here are some common issues you might encounter and how to solve them:

Router Not Responding After Reset

If your router doesn't seem to be working after a reset, try unplugging it for a full minute before plugging it back in. This can help clear any residual power and allow for a fresh start.

Unable to Connect to WiFi After Reset

Double-check that you're using the correct default network name and password. If you're still having trouble, try connecting via an Ethernet cable to access the router settings.

Lost Internet Connection Post-Reset

You may need to contact your internet service provider to reset your connection on their end. Some providers require you to register your router's MAC address after a reset.

Alternative Reset Methods for TP-Link Routers

If you have a TP-Link router, you have a couple of additional options for resetting:

Using the Router Admin Panel

Log into your router's admin panel and look for a "Reset" or "Restore Factory Defaults" option in the settings menu.

Resetting Through Mobile App

Some TP-Link routers can be reset using the TP-Link Tether mobile app. Look for a reset option in the app's settings.

Resetting your WiFi router doesn't have to be a daunting task. With these steps, you can troubleshoot many common internet issues and get back online quickly. Remember to keep your router's firmware updated for optimal performance and security. If you continue to experience problems after a reset, it may be time to contact your internet service provider or consider upgrading to a new router.

FAQ (Frequently Asked Questions)
