In Administering Windows Server Hybrid Core Infrastructure, Microsoft states that the domain password policy for domain user accounts is determined by the GPO that wins at the domain root (commonly the Default Domain Policy). GPOs linked to OUs do not change the domain password policy for user accounts in those OUs; they only affect local accounts on computers within those OUs unless Fine-Grained Password Policies (PSOs) are used and scoped to users/groups. The case shows Default Domain Policy in contoso.com sets Minimum password length = 10. Therefore, both Admin1 (a domain user in Contoso\OU1) and User1 (in Contoso\OU3) fall under the 10-character minimum; the OU-linked GPO1 (14) does not override the domain password policy for their domain accounts → Admin1: No, User1: Yes.

For member servers and local accounts, the documentation explains that password policy settings in a GPO linked to the OU containing the computer apply to that computer’s local Security Accounts Manager (SAM). In the scenario, Server1 resides in Member Servers and GPO2 linked to Member Servers specifies Minimum password length = 8. Thus, when Admin1 creates a local account on Server1, the enforced minimum is 8 characters → Yes. This approach follows least privilege and standard precedence: domain-level for domain accounts, OU-linked GPOs for local accounts, unless PSOs are explicitly defined.

One possible solution to configure SRV1 as a DNS server that can resolve names from the contoso.com domain by using DC1 and all other names by using the root hint servers is to use conditional forwarding. Conditional forwarding allows a DNS server to forward queries for a specific domain name to another DNS server, while using the normal forwarding or root hint servers for other queries. Here are the steps to configure conditional forwarding on SRV1:

On SRV1, open DNS Manager from the Administrative Tools menu or by typing dnsmgmt.msc in the Run box.

In the left pane, right-click on Conditional Forwarders and select New Conditional Forwarder.

In the New Conditional Forwarder dialog box, enter contoso.com as the DNS Domain name.

In the IP addresses of the master servers box, enter the IP address of DC1, which is the DNS server for the contoso.com domain. You can also click on Resolve to verify the name resolution of DC1.

Optionally, you can check the box Store this conditional forwarder in Active Directory, and replicate it as follows if you want to store and replicate the conditional forwarder in AD DS. You can also select the replication scope from the drop-down list.

Click OK to create the conditional forwarder.

Now, SRV1 will forward any queries for the contoso.com domain to DC1, and use the root hint servers for any other queries. You can test the name resolution by using the nslookup command on SRV1 or another computer that uses SRV1 as its DNS server. For example, you can run the following commands:

nslookup www.contoso.com

nslookup www.microsoft.com

The first command should return the IP address of www.contoso.com from DC1, and the second command should return the IP address of www.microsoft.com from a root hint server.

TASK 5

👉 Objective:

Configure a Group Policy Preference to create a shortcut to \\srvi.contoso.com\data on the desktop of users in the Server Admins OU.

Step-by-Step Guide: Using Group Policy Preferences to Create a Desktop Shortcut

✅ Step 1: Open Group Policy Management Console (GPMC)

Log in to a DC or a management computer with RSAT installed.

Open Group Policy Management (gpmc.msc).

✅ Step 2: Create a New GPO

In the GPMC console, expand the forest and the domain (e.g., contoso.com).

Right-click the OU named Server Admins and select Create a GPO in this domain, and Link it here.

Name the GPO, e.g., Desktop Shortcut for Server Admins.

✅ Step 3: Edit the GPO

Right-click the newly created GPO and select Edit.

This opens the Group Policy Management Editor.

✅ Step 4: Navigate to User Preferences

In the editor, expand:

User Configuration > Preferences > Windows Settings > Shortcuts.

✅ Step 5: Create the Shortcut

Right-click Shortcuts and select New > Shortcut.

In the New Shortcut Properties window:

Action: Create

Name: Data Folder

Target Type: File System Object

Location: Desktop

Target Path: \\srvi.contoso.com\data

Optionally, set an icon or description if you want.

✅ Step 6: Configure Item-Level Targeting (Optional)

If you want to limit this shortcut strictly to specific users/groups, click the Common tab.

Check Item-level targeting and configure conditions (optional).

For this scenario, linking the GPO to the Server Admins OU is usually sufficient.

✅ Step 7: Close and Update

Close the editor.

In GPMC, ensure the GPO is linked to the Server Admins OU.

Force a Group Policy Update on client computers:

On a client computer:

gpupdate /force

Or wait for the next Group Policy refresh cycle.

✅ Step 8: Verify

Log in as a user in the Server Admins OU.

The shortcut to \\srvi.contoso.com\data should appear on the desktop.

To deploy a new primary DNS zone named fabrikam.com to DC1 and sign the zone, you can follow these steps:

Step 1: Create the Primary DNS Zone Use the Add-DnsServerPrimaryZone PowerShell command to create the primary zone:

Add-DnsServerPrimaryZone -Name "fabrikam.com" -ZoneFile "fabrikam.com.dns" -DynamicUpdate Secure

This command creates a primary zone for fabrikam.com with a DNS file named fabrikam.com.dns and allows secure dynamic updates.

Step 2: Sign the Zone To sign the zone, you can use the DNS Manager or Windows PowerShell. Here’s how to sign the zone using PowerShell:

Add-DnsServerSigningKey -ZoneName "fabrikam.com" -Type KeySigningKey -CryptoAlgorithm RsaSha256

Set-DnsServerDnsSecZoneSetting -ZoneName "fabrikam.com" -DenialOfExistence NSEC3 -NSEC3Parameters 1,0,10,""

These commands add a signing key to the zone and set DNSSEC settings with NSEC3 parameters.

Step 3: Publish the Signed Zone After signing the zone, ensure that it is published and available for DNS queries. You can verify the zone signing status using the following command:

Get-DnsServerZone -Name "fabrikam.com"

Note: Ensure that you have the appropriate permissions to perform these actions on DC1 and that the DNS Server role is installed and properly configured. Also, replace "fabrikam.com.dns" with the actual path to your DNS file if it’s different12.

By following these steps, you should be able to deploy and sign the new primary DNS zone fabrikam.com on DC1.

One possible solution to configure Hyper-V to ensure that running virtual machines can be moved between SRV1 and SRV2 without downtime is to use Live Migration. Live Migration is a feature of Hyper-V that allows you to move a running virtual machine from one host to another without any noticeable interruption of service. To set up Live Migration between SRV1 and SRV2, you need to perform the following steps:

On both SRV1 and SRV2, open Hyper-V Manager from the Administrative Tools menu or by typing virtmgmt.msc in the Run box.

In the left pane, right-click on the name of the server and select Hyper-V Settings.

In the Hyper-V Settings dialog box, select Live Migrations in the navigation pane.

Check the box Enable incoming and outgoing live migrations.

Under Authentication protocol, select the method that you want to use to authenticate the live migration traffic between the servers. You can choose either Kerberos or CredSSP. Kerberos does not require you to sign in to the source server before starting a live migration, but it requires you to configure constrained delegation on the domain controller. CredSSP does not require you to configure constrained delegation, but it requires you to sign in to the source server through a local console session, a Remote Desktop session, or a remote Windows PowerShell session. For more information on how to configure constrained delegation, see Configure constrained delegation.

Under Performance options, select the option that best suits your network configuration and performance requirements. You can choose either TCP/IP or Compression or SMB. TCP/IP uses a single TCP connection for the live migration traffic. Compression uses multiple TCP connections and compresses the live migration traffic to reduce the migration time and network bandwidth usage. SMB uses the Server Message Block (SMB) 3.0 protocol and can leverage SMB features such as SMB Multichannel and SMB Direct. For more information on how to choose the best performance option, see Choose a live migration performance option.

Under Advanced Features, you can optionally enable the Use any available network for live migration option, which allows Hyper-V to use any available network adapter on the source and destination servers for live migration. If you do not enable this option, you need to specify one or more network adapters to be used for live migration by clicking on the Add button and selecting the network adapter from the list. You can also change the order of preference by using the Move Up and Move Down buttons.

Click OK to apply the settings.

Now, you have configured Hyper-V to enable live migration between SRV1 and SRV2. You can use Hyper-V Manager or Windows PowerShell to initiate a live migration of a running virtual machine from one server to another.
