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 ensure that a DHCP scope named scope1 on SRV1 can service client requests is to activate the scope on the DHCP server. A scope must be activated before it can assign IP addresses to DHCP clients. To activate a DHCP scope on SRV1, perform the following steps:

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

In the left pane, expand your DHCP server and click on IPv4.

In the right pane, right-click on the scope that you want to activate, such as scope1, and select Activate.

Wait for the scope to be activated. You can verify the activation status by checking the icon next to the scope name. A green arrow indicates that the scope is active, while a red arrow indicates that the scope is inactive.

Now, the DHCP scope named scope1 on SRV1 can service client requests and lease IP addresses to DHCP clients. You can test the DHCP service by using the ipconfig /renew command on a DHCP client computer that is connected to the same subnet as the scope.

One possible solution to ensure that the Azure file share named share1 can sync to on-premises servers is to use Azure File Sync. Azure File Sync allows you to centralize your file shares in Azure Files without giving up the flexibility, performance, and compatibility of an on-premises file server. It does this by transforming your Windows Servers into a quick cache of your Azure file share. You can use any protocol available on Windows Server to access your data locally (including SMB, NFS, and FTPS) and you can have as many caches as you need across the world1.

Here are the steps to configure Azure File Sync for the Azure file share named share1 and the source files located in a folder named \dc1.contoso.com\install:

On the Azure portal, create a Storage Sync Service in the same region as your storage account that contains the Azure file share named share1. For more information on how to create a Storage Sync Service, see How to deploy Azure File Sync.

On the on-premises server that hosts the folder named \dc1.contoso.com\install, install the Azure File Sync agent. For more information on how to install the Azure File Sync agent, see Install the Azure File Sync agent.

On the on-premises server, register the server with the Storage Sync Service that you created in the first step. For more information on how to register a server with a Storage Sync Service, see Register/unregister a server with Storage Sync Service.

On the Azure portal, create a sync group that defines the sync topology for a set of files. In the sync group, select the Azure file share named share1 as the cloud endpoint and the folder named \dc1.contoso.com\install as the server endpoint. For more information on how to create a sync group, see Create a sync group and a cloud endpoint and Create a server endpoint.

Wait for the initial sync to complete. You can monitor the sync progress on the Azure portal or on the on-premises server. For more information on how to monitor sync progress, see [Monitor sync progress].

Once the initial sync is complete, you can add more on-premises servers to the same sync group to sync and cache the content locally. You can also enable cloud tiering to optimize the storage space on the on-premises servers by tiering infrequently accessed or older files to Azure Files.

To collect the recommended Windows Performance Counters from SRV1 in a Log Analytics workspace, you can follow these steps:

Step 1: Access the Log Analytics Workspace Log in to the Azure portal and navigate to your Log Analytics workspace.

Step 2: Configure Performance Counters In the Log Analytics workspace, select Advanced settings and then choose Data > Windows Performance Counters1. You can add the recommended performance counters by selecting the + button. If you’re using legacy agent management, you can add counters from the Legacy agents management menu2.

Step 3: Add Performance Counters Select the counters you want to collect. You can add common counters quickly by checking the boxes next to them. For specific counters, enter the name of the counter in the format object(instance)\counter. For example, to collect the Processor Time counter for all instances of the Processor object, specify Processor(_Total)\% Processor Time.

Step 4: Set Sample Interval When adding a counter, you can set the sample interval, which is the frequency at which data is collected. The default is 10 seconds, but you can change this to a higher value if needed.

Step 5: Apply Configuration After adding the desired performance counters, select Apply at the top of the screen to save the configuration.

Step 6: Install and Configure the Agent Ensure that the Microsoft Monitoring Agent (MMA) is installed on SRV1. Configure the agent to report to your Log Analytics workspace by specifying the workspace ID and key during setup.

Step 7: Verify Data Collection After the agent is configured, it will start collecting the specified performance counters. You can verify the data collection in the Log Analytics workspace by running queries against the collected data.

Note: The legacy Log Analytics agent will be deprecated by August 2024. Migrate to the Azure Monitor agent before this date to continue ingesting data3.

By following these steps, you should be able to collect the recommended Windows Performance Counters from SRV1 in your Log Analytics workspace. Ensure that you have the necessary permissions and that SRV1 has network connectivity to Azure services.
