It depends on the services that you enable on the DNS Server.
You can create a PowerShell script to automate some of these checks.
For example, you can use PowerShell cmdlets like Test-NetConnection
, Resolve-DnsName
, and Get-WinEvent
to perform some of the checks programmatically.
Hello there,
Performing a DNS health check on a Windows Server 2019 involves several steps. Here's a guide on how to do it:
Check DNS Service Status:
Ensure that the DNS service is running. To do this:
Press Win + R, type services.msc, and hit Enter.
Look for the "DNS Server" service in the list, and check its status. It should be "Running."
Verify DNS Zones:
Check if all DNS zones are present and properly configured.
Open the DNS Manager: Press Win + R, type dnsmgmt.msc, and hit Enter.
Expand your server node and check the "Forward Lookup Zones" and "Reverse Lookup Zones" for your DNS zones.
Check DNS Records:
Ensure that all required DNS records are present and correct.
Look for essential records like A, AAAA, CNAME, MX, PTR, etc., and verify their settings.
Check DNS Server Event Logs:
Check the event logs for any DNS-related errors or warnings that might indicate issues.
Go to Event Viewer (Press Win + R, type eventvwr.msc, and hit Enter).
Navigate to Windows Logs > System and look for events with the Source "DNS Server."
DNSSEC (Domain Name System Security Extensions):
If you're using DNSSEC, verify its status.
Open the DNS Manager, right-click on your server node, and select "Properties."
Go to the "DNSSEC" tab and check the DNSSEC status.
DNS Cache:
Check the DNS cache to ensure that it's not causing any problems.
Open Command Prompt or PowerShell as an administrator.
To display the current DNS cache entries, run the command: ipconfig /displaydns.
To flush the DNS cache, run the command: ipconfig /flushdns.
DNS Diagnostics (Optional):
Windows Server 2019 includes built-in DNS Diagnostics that can help troubleshoot issues.
Open Command Prompt or PowerShell as an administrator.
Run the command: dnscmd /Diagnose to perform DNS diagnostics.
