Pages not being served on first try.

We have a problem that is seriously stumping us. We have
2 identical (in configuration) Web Servers both running
IIS 6.0 on Windows 2003 boxes. They are at different
sites in the US, and we use one for a warm backup or
failover solution of the other. On our main server, we
host web pages 90% of the time with no problems. When we
do a transfer to the second server and change all of our
DNS entries, the pages it serves up (asp) will not load on
the first connect more than half of the time, but in
almost all situations, when we hit refresh after the first
failure, the pages come up fine and will work without a
problem for the whole session. We get 'Cannot find server
of DNS error.' If you disconnect and wait a few minutes to
reconnect again, the same issue happens. Any ideas? We
have tried monitoring the internet traffic and server load
at failure times and both are negligible.

Thanks.

Doing me a favour: when you switch to the backup, turn of "HTTP Friendly Errors" in Internet Explorer,
empty your cache and then Copy/Paste the error message you get when you hit the backup server.


Thank you.
