Windows Small Business Server 2011 Standard allows a maximum of 75 user accounts and computers. If you have more than this, use the Windows SBS Console to remove some computers or user accounts.
Once you start to get this error you’ll get it once a day until the issue is resolved. The problem is that SBS is detecting that your active directory contains more than 75 objects in a category. So it’s time to clean up your AD.
Here how I go about it:
1. Move all service accounts and templates into the Manage Service Account container. This container is new-ish active directory and is designed to house all of those service accounts that have to exist but aren’t really users. This exempts them from licensing.
2. Delete those user and computer accounts that haven’t logged in, in a long time.
First you need to identify them. To find computer accounts that haven’t logged in, in 4 weeks run this command: dsquery computer –inactive 4 Then move those machines into a ToBeDeleted OU so you can verify that they truly no longer exist. Do the same for user accounts. Once you have identified the accounts to be removed, delete them.
It’s not difficult to clean up your Active Directory. This maintenance activity should be done on a regular basis in all environments whether small or large. Regardless of the size it will help you stay within your purchased CAL limit.
