Vulnerability V-259349

Note: Due to the manner in which Active Directory replication increments SOA records for zones when transferring zone information via Active Directory (AD) replication, this check is not applicable for AD-integrated zones. 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 SOA information for the zone and obtain the Serial Number. Access each secondary name server for the same zone and review the SOA information. Verify the Serial Number is the same on all authoritative name servers. If the Serial Number is not the same on one or more authoritative name servers, this is a finding.

If all DNS servers are AD integrated, determine why the replication is not taking place to the out-of-sync secondary name servers and mitigate the issue. 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. Initiate a zone transfer to all secondary name servers for the zone.
