# AD part 1 ### Active Directory "I built an Active Directory environment from scratch on bare metal hardware — including installing Windows Server 2019, promoting a Domain Controller, building an OU structure that mirrors a real company, and joining client machines to the domain." "I've configured Group Policy Objects and verified their application using gpresult, including troubleshooting scope and filtering issues when policies weren't applying as expected." "I understand the DNS dependency in Active Directory environments — I configured a DC as its own DNS server using the loopback address and pointed client machines to the DC for domain resolution." *** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
