IIS authentication

I am having a problem where certain users cannot authenticate via OWA on the
first try, for example; https://owa.compan.com/exchange, prompt for cert -
ok, user = domain\user, pass, some frames on the page start to build, but the
logon prompt kicks back. You can click ok 3 times and it leaves you at a 401
unauthorized message. Then oddly enough, if you just refresh th browser, it
lets you right into the mailbox. This is Exch 2000 running in 2003 AD. Does
not happen for all users, and I cannot find a common thing (group, OU, etc)
that would or wouldn't allow this. If I try this from inside the network from
a server via browser it is fine, only from outside does it fail.
ANy ideas?
