On the 2008 domain controller ... you need to make those changes.
</div>


<div>
<div class="content wysiwyg-content">
I have my old domain, 2000, and a new 2008 domain. The trust is setup and functioning.<br />
<br />
When I try to authenticate to a web site on the 2008 domain from the 2000 domain I cannot authenticate using integrated authentication. If I set the authentication to basic it authenticates fine.<br />
<br />
How do I get the integrated authentication to work from a 2000 domain to a 2008 domain?
