our workstations are configured such that the primary DNS Server is our
netware 6.5 SP3 server.

we have a record so that host.location.com points to an internal server.

howerver, host.location.com to the outside world also exists as a public IP
in the secondary DNS (our ISPs DNS server)

after a while, the workstation uses the public IP instead of the private IP.
I have to do a ipconfig /flushdns and sometimes a ipconfig /registerdns in
order for the workstation to use the private ip host.location.com

any help would be appreciated.
