Check the DNS cache on client computer

Here’s a tip from my colleague Ed Wilson (the Microsoft Scripting Guy) about how to use PowerShell to check the DNS cache on client computers:

Question: You suspect DNS corruption on several of your client Windows 8.1 computers. How can you check this out?

Answer: Use the Invoke-Command cmdlet to run the Get-DNSClientCache cmdlet on the suspect computers. The following example, runs the Get-DNSClientCache cmdlet on three different computers, and looks for records related to Bing.

Invoke-Command -script {Get-DnsClientCache -Name “*bing*”} -ComputerName c1,c2,c3

           NOTE: you will need to run the above command with admin rights
