By default, an Active Directory domain allows any authenticated domain user to join workstations in the domain. The limit is 10 times. You may need to increase or decrease this limit for enterprise needs.
Go to the DC server and open the ADSI Edit MMC. Right-click on your domain and select “Properties“

Now, find the attribute called ms-DS-MachineAccountQuota. You can set the value to 0 which means no limit.

Please note that this limit is not applied for any user account which is a member of domain admins or enterprise admins group.
You can use PowerShell to get the value:
PS > Get-ADDomain | Get-ADObject -Properties 'ms-DS-MachineAccountQuota'
