Hi, I have Exchange 2k & SP2 running on a W2k Standard Server with SP2 and also WebAdmin (The ASP tool to manage hosting) if a domain member logs onto http://webmail.domain/exchange and use Win XP & IE6 there is no problem, but if using W98 to Win 2k with IE5 or 6 they are asked for a Domain as well in the logon dialog, no matter what combination you enter results in a refused logon. All users have a primary domain account and are a member of the hosted domain (with the primary smtp pointing to their subscribed domain) Any ideas ? Craig
