When I run the command to Import-Module DnsShell, I get this error and I dont know why..

PS C:\windows\system32> Import-Module DnsShell

'file:///C:\windows\system32\WindowsPowerShell\v1.0\Modules\DnsShell\DnsShell.dll' or    one of its dependencies. Operation is

Note: I would have posted pictures but I needed a rep of at least 10 in serverfault

Look at the file properties on DnsShell.dll and see if, on the general tab, you see an Unblock button at the bottom. This can happen if you download the files from a remote source.

This is due to the version of PowerShell you are running. This module runs with 2.0 ONLY. If you are getting the error run 2.0 by running "powershell.exe -version 2.0" Then import the module.
