I installed Parallels 5.0 using the Boot Camp option - following the suggestion of creating the two different hardware configurations, etc... All seems to be running really well... until I try to access a webpage that requires our windows authentication to open it... It actually worked yesterday right after the initial installation... but, I logged off windows last night, logged back in today... now, when I go to Internet Explorer, the site won't even come up - page not found (other websites do work, so I have internet connectivity)... Also, I can access the site via Safari (mac side) and Firefox (within Windows) ... which both drop down the login screen... IE should be doing this natively, I thought... what can I be missing? I've disabled the block pop ups... I've check security settings.. I've added the site to my trusted sites... Unfortunately, the site design only works in IE (not friendly with Safari/Firefox).... Thanks for any help. Jill
