I am having a problem in that IE7 appears to be using DNS before the HOSTS
file
during name resolution. This is backwards or opposite from how the system
(Windows XP) processes name resolution.

Using IE7 to access a page/resource on a machine (name in HOSTS only, not
DNS) requires about 15 seconds to load.

Add the pc entry to DNS and IE7 loads the page instantly. Remove the
entries and the degredation returns.
Remove DNS entries from TCP/IP stack of the client and the page loads
instantly again.

Awaiting comments, suggestions, etc...

I am having the same issue with IE7 not using my hosts file. Did you ever find an answer to this?

Thanks.

In the first place, learn how to quote posts you are responding to. My
client is configured to purge older posts sooner than the server, so I was
able to find the original post on the server; but I have seen responses to
posts so old that not even Google had the original. Damned hard to figure
out why you are saying what you are saying with no context.

If using a very large hosts file (usually to redirect offensive pages), such
a delay as described could occur, depending upon whether 'lmhosts' is also
being used, and/or the system is in an NT Domain network.

Also, if the redirect IP address is, '127.0.0.1', changing it to '0.0.0.0'
may help. Or going from '0.0.0.0' to 127.0.0.1'.
