Win2k caches ip addr. after name resolution from dns?

[Sanjivendra Nath]

Is there anyway for us to force the MS clients (namely, IE 5.0) to go to the
DNS for name resolution always, or at least limit the time during which it
caches the ip address of a site?

I've tried 4 clients now against my DNS running Bind9 on linux with
roundrobin setup to 2 webservers behind it.

* linux client, win95, win98 - consecutive pings average out to 50% load on
each webserver.

* win2k - consecutive pings sticks to the first ip address of the webserver
served by my DNS.

Thanks,
Sanju.
