security local intranet zone

hello newsgroups

i have a intranet-server (iis 2003) in our intranet. the server is member of
our domain. on this intranet-server is a web running with "disabled
anonymous access" and integratet windows authentication.

if a user (with IE6) go to this intranet-web, always appears the login-mask
(domain\user + password).
if i add this web to the intranet-security-zone, it works without this
login-mask. but i have to do this on every workstation in our network. is
there another solution to tell all the clients to trust my intranet-web?

thanks
markus
