How to DNS round robin webservers using IE

I have a webserver farm. The webservers all have the same domain name and
multiple IP addresses. The DNS server for this webserver does round robin
handing out of IP addresses for this domain name.

I verify that the DNS server does correct round robin handing out of IP
addresses by doing

ipconfig /flushdns
nslookup webserver.domain.com

repeatedly on the windows machine. However, when I try to connect to
webserver.domain.com from IE I always go to the same ip address in the farm.

I have set DnsCacheTimeout and ServerInfoTimeOut to 0 in IE and restarted IE
but I still get the same result.

Is it not possible to round robin schedule requests to webservers in a farm
by using DNS robin robin records ?
