MSP Extensions allows you to activate or deactivate a domain, which cascades the
activation status to companies in the domain.
When you activate a company record, MSP Extensions automatically activates the
company's associated domain. For example, if you activate the ACME company, then you
also activate the TOP/ACME domain.
Navigate to the domain record.
Clear the Active check box to deactivate the domain, or
select the check box to activate the domain.
Warning: Do not delete domains. Deactivate domains that you no
longer need instead of deleting them.
