are you using phpbb? if so go to your ACP (admin control panel) and click on General Admin -> Configuration and find your Cookie settings. now just change the names around and add a backslash instead of the name "/"

also in your General Board Settings change the Script path to "/" and domain name to new domian.

hope this helps

I search http://www.php.net/ ...
the problem is that IE cannot update cookie , if subdomain name is over 10 char.
