OK- so it works internally from \\exchserver\exchange, but not 
www.you.com\exchange... Does it ask for authentication when they use the 
local NetBIOS name?
If not (and you indeed want to use the NT Integrated you have selected) you 
probably need to add the www.you.com domain to the intranet sites in IE and 
ensure that auto-logon only in Intranet is selected under security settings.

And just for a test (you can easily revoke it) give your "domain users" log 
on locally rights and try it.  Just for fun.  Let me know what that does.

Let me know what each does, and I'll go back and look at the exact same 
config I have on a test network (Ex2k on DC behind ISA).  However, I am 
using Server Publishing, not Web Publishing- I wonder if that is why...

Let me know.

Thanks!
