Log on to the DNS server using the Domain Admin or Enterprise Admin account or Local Administrator account.

Press the Windows key + R and execute "dnsmgmt.msc".

On the opened DNS Manager snap-in from the left pane, expand the server name for the DNS server and then expand "Forward Lookup Zones".

From the expanded list, click to select the zone.

Review the zone's RRs and verify HINFO, RP, and LOC RRs are not used. If TXT RRs are used, they must not reveal any information about the organization that could be used for malicious purposes.

If there are any HINFO, RP, LOC, or revealing TXT RRs in any zone hosted by the DNS server, this is a finding.
