Check out how many users or computers are authenticated in a given Domain Controller

Question

I found a script to check out how many users or computers are authenticated in a given Domain Controller.

The Script can be found here: https://gallery.technet.microsoft.com/scriptcenter/Check-out-how-many-users-05a8b499#content

Running this under a Server 2008 R2 Domain Controller gives two Errors:

• $AccountName = ($RegexAccountName.match($_.message).value).Split(":")[1].Trim <<<< ()
  • CategoryInfo : InvalidOperation: (Trim:String) [], RuntimeException
  • FullyQualifiedErrorId : InvokeMethodOnNull
• $DomainName = ($RegexDomainName.match($_.message).value).Split(":")[1].Trim <<<< ()
  • CategoryInfo : InvalidOperation: (Trim:String) [], RuntimeException
  • FullyQualifiedErrorId : InvokeMethodOnNull

Any thoughts on how to run this under Server 2008 R2?

Answer 1

I don't think this has anything to do with the fact of it being Windows Server 2008 R2.

My guess is that you're running non-english Windows Server. Adjust the following lines to match your language:

[regex]$RegexAccountName = "Account Name:\s+\w+.*" [regex]$RegexDomainName = "Account Domain:\s+\w+.*" 

After doing that on my test machine, it worked fine.

I would suggest you find one of the events the script is running for to find the exact wording used in your language.

Answer 2

If your primarily after "how many" and not which users or how often, you can get those numbers from the Server object in Perfmon. It has values for "Logons Total" and "Logons/sec"
