Hi guys, I know this might be a fool question but I hope you can help me out with this: I have set up a Win2K server with Exchange 5.5 and IIS up and running. Btw, the Exchange server is on another machine. Alright, everything's okay except for a small detail in the Webmail interface. When accessed from the intranet, the validation process asks only for an alias, then a username and a password, and everyone with rights can enter perfectly. But when accessed from outside (like from my home via internet), it also asks for a domain. No matter how I enter my data, it won't allow me access. I tried entering "domain\username", leaving the domain field blank, whatever, with no results. I know I can make the webmail not to ask for a domain, because the webmail server was located in a NT4 server before and it did so, but seemingly I cannot find where to touch that in this new server. Can anyone help me? Thanks! Andrés
