Also to note, My final points in the “differences section” were more picky than anything. You are absolutely correct that the processing power required for the loop would be minimal.

One last item, the Fully Qualified Domain Name of the current domain can be returned quickly by using:
[String]$FQDN = [System.DirectoryServices.ActiveDirectory.Domain]::getCurrentDomain()

As with the Distinguished Name of the current domain with:
$root = [ADSI]”
$CurrentDN = $root.DistinguishedName

When I found these out — my beautiful FQDN to DN converter was useless and I wanted to cry.

Thanks for taking the time to review and comment!!

During the development process, I shifted mid-stream and didn’t go back to rename them.

I didn’t write “optimized” code since the number of iterations needed to go through an FQDN is relatively small. The added overhead of assigning the $Separator variable inside the for loop is minimal, at best. You are correct, though, that moving it outside of the loop is more efficient.

I also tend to explicitly define the input variables (parameters) to my functions.

In short, a very good post and I appreciate the feedback. I will probably take your suggestion regarding the inaccurate variable names.

Thanks!
