Unique Computer Name Generation

Question

Hello, I am trying to lock down machine creation to a specific OU and would like to create the machine name with a unique number. 
 For example I would like to create the machine name with the name of the OU it will be placed in, followed by 3 unique numbers. The generation policy does not allow me to create unique numbers as part of the computer name. 
 I have to believe this is a pretty canned answer, but cannot seem to figure it out. Any suggestions would be helpful. 
 Thanks, 
 Alex

Hello, Alex. 
 You can create a canned (Property Generation and Validation) policy to enforce your naming convention, however if you wish the policy to assign a numerical/unique value automatically, then you're going to need to script it. 
 The version of your rule that simply enforces your standard would look like this: 
 
 'Name (ou)' of parent OU, followed by 
 '-', followed by 
 3 characters [0-9] (required) 
 
 In this case I put a hyphen separator between the parent OU name and the numerical requirement. 
 If you're looking for the scripted version, there is some (very old) sample code posted here . What you're requesting is manageable and plausible: I've created similar, automatic name generation scripted policies before. Unfortunately they are highly customer-specific, hence are not/cannot be posted here. There may be other samples here in the forums that I didn't find in my quick search before posting this.
