I get the following warning on the console:

named: default: warning: check_hints:
A records for J.ROOT-SERVERS.NET class
1 do not match hint records

What does this mean and what can I do to correct it.

This message indicates that your current root hint file is out of date and should be updated. You can download the new version of the root hints file from ftp://ftp.rs.internic.net/domain/named.root

You will want to replace your current root hint file with the named.root referenced above. By default the root hint file is :

MultiNet - MULTINET:DOMAIN-NAME-SERVICE.CACHE
TCPware - TCPWARE_NAMED_ROOT:NAMED.CA

On recent versions of VMS and FTP access from your MultiNet or TCPware system you can use the following commands to copy the new version of the hint file and restart the named server

For MultiNet:

$ copy/ftp/log ftp.internic.net::"/domain/named.root" - multinet:domain-name-service.cache
$ multinet netcontrol domain restart

For TCPware:

$ copy/ftp/log ftp.internic.net::"/domain/named.root" - tcpware_named_root:named.ca
$ @tcpware:restart dns
