How to fix “Exceeded the Maximum Number of Computer Accounts Allowed to Create in this Domain”

This is a quick post about a problem I saw in my lab today, basically computers were failing to join the domain, and to find out why, I manually attempted domain join using the account specified in the SCCM Task Sequence. When doing so I got the following error:

On the client computer that failed to join the Domain, you can browse the netsetup.log in C:\Windows\Debug folder, and you should see something similar to the text below.

The fix involves changing a value in an Active Directory attribute.


To fix this, on the domain controller, start up adsiedit.msc and browse to the DC=…  of your domain. Select it and right click, choose Properties.

Note: If you cannot find DS-MachineAccountQuota when you select Properties, then ensure that you have connected to the Default naming context in ADSI Edit (and not some other context such as Schema, RootDSE or Configuration. To change the context, select ADSI Edit in the left pane, then click on Action, and then Connect to.

Select Default Naming Context.

Once done, you’ll be able to find the ms-DS-MachineAccountQuota attribute by selecting Properties.

Scroll down to ms-DS-MachineAccountQuota, notice that the default value is 10.

and change it to something larger, like 1000.

Job done !
