DNSLint is a command-line Microsoft utility designed to help you diagnose common DNS name resolution issues. DNSLint can be downloaded from the Microsoft Download Center. DNSLint has three functions that verify Domain Name System (DNS) records and generate an HTML report. The three functions are:

dnslint /d: This diagnoses potential causes of "lame delegation" and other related DNS problems.
dnslint /ql: This verifies a user-defined set of DNS records on multiple DNS servers.
dnslint /ad: This verifies DNS records specifically used for Active Directory replication.

DNSLint syntax is:

dnslint /d domain_name | /ad [LDAP_IP_address] | /ql input_file
[/c [smtp,pop,imap]] [/no_open] [/r report_name]
[/t] [/test_tcp] [/s DNS_IP_address] [/v] [/y]
