The simplest method of using DNSLINT is to verify DNS records for domain
controllers. To do this, run:
DNSLINT /AD IP of dc you want to check /S IP of DNS server authoritative for MSDCS
It also has the /QL functionality in order to check SRV records and the like.
This will run and generate an HTML-based report of records on this DNS server for
AD, confirming that CNAME records match up with A records. The easiest way to
interpret the results is to scroll to the very bottom of the page and look at the
summary report - any warnings or errors will be noted. All issues in the body of
the report are color-coded for easy viewing as well.
