Powershell script change DNS

Hi Experts,

I'm trying to run the script from here out of the box

https://gallery.technet.microsoft.com/Modify-DNS-Server-0ec651e7

BatchModifyDNSConfiguration.ps1 -OU 'OU=FAKE GROUP, OU=FAKE,DC=DOMAIN,DC=com' –OldsDNS 192.168.9.9 –NewDNS 192.168.9.99

Get-ADComputer : An empty SearchBase is only supported while connected to a GlobalCatalog.
At C:\Users\olujan\Desktop\BatchModifyDNSConfiguration\BatchModifyDNSConfiguration\BatchModifyDNSConfiguration.ps1:57 char:12
+ $Servers = Get-ADComputer -SearchBase "$DistName" -Filter "*" | ForEa ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Get-ADComputer], ArgumentException
+ FullyQualifiedErrorId : ActiveDirectoryCmdlet:System.ArgumentException,Microsoft.ActiveDirectory.Management.Commands.GetADComputer

I've tried with single and double quotes, re-order the switches... Feels like I'm making a rooking mistake. What am I doing wrong?

Thanks I knew it was a rookie mistake

Really the only way to see it is to look at the code since there isn't any built-in help or examples. Since the error mentions line 57, go there first. The error also mentions an empty searchbase, and the command on line 57 references $DistName for the -searchbase parameter. From there you go back to see how $DistName is defined. That's pretty much the flow of how you begin to debug a problem.
