Description
The Clear-DnsServerCache cmdlet clears resource records from a Domain Name System (DNS) server cache.
Examples
Example 1: Clear resource records from the cache
PS C:\> Clear-DnsServerCache -ComputerName "Win12S-05.DNSServer-01.Contoso.com" -Force
This command clears the DNS server cache on a specified DNS server. If you do not use the Force parameter, you must confirm the action before it is performed.
Optional Parameters
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
The cmdlet immediately returns an object that represents the job and then displays the command prompt.
You can continue to work in the session while the job completes.
To manage the job, use the
*-Job
cmdlets.
To get the job results, use the
Receive-Job
cmdlet.
For more information about Windows PowerShell background jobs, see about_Jobs .
