Here's the simplest scenario for my problem, left to right.

I am using an IE6 Browser on a corporate network that has to jump =
through one or more firewalls to get to any web server.
I point my browser to an HTTPS IIS6 site (SITE A) that is sitting behind =
a Cisco CSS (Round Robin Load Balancer) with 3 servers in the mix.
That site redirects my browser (HTTP 302) to an HTTPS IIS5 site (SITE B) =
that is sitting behind a Cisco CSS (Round Robin Load Balancer) with 10 =
servers in the mix.

On occasion, like 1 out of 10 times, I get the message "Cannot find =
server or DNS error" on the redirect to (SITE B).
I change the hosts file and test individually pointing to each of the 10 =
(SITE B) servers , and there are no problems.

The problem seems to happen more when the network is under load, =
although this may be coincidental.

For a time today, I got the error every 3 or 4th attempt. One half hour =
later, I tried 10 times in succession, and could not get the error to =
occur even once.

This problem appears to be intermittent, although frequent enough to =
call for a solution.

I have a virtual free ticket to Hawaii for the person who can give me =
enough clues to solve this problem. (Virtual as-in just-pretend) :)

Thanks in advance
