Windows PowerShell script that helps you to find unregistered subnets by Alexandre Augagneur

DS-MVP Alexandre Augagneur has added a Windows PowerShell script to the TechNet Script Center Repository. This script can help you locate IP v4 subnets that you may want to add as Active Directory Domain Services (AD DS) sites. The script, called Collect-MissingADSubnets, helps you to review client logon attempts from the domain controllers where no matching site was found (NO_CLIENT_SITE). You can export the results to a spreadsheet and check them against your network environment. For more scripts from Alexandre, search on Alexandre Augagneur in the TechNet Gallery.
