Exceeded the Maximum Number of Computer Accounts Allowed to Create in this Domain

 It happens because of default AD ms-DS-MachineAccountQuota value which is 10.

The workaround is to delegate custom rights for specific account:

1. Open the Active Directory Users and Computers snap-in.

2. Right-click the container under which you want the computers added, and press Delegate Control.

3. Press Next.

4. Press Add.

5. After adding all the users and/or groups, press Next.

6. Select Create custom task to delegate and press Next.

7. Select Only the following objects in the folder, check Computer objects, check the Create selected objects in this folder box, and press Next.

8. Check the Create all child object box and press Next.

9. Press Finish.
