Everything was working fine until I rebooted my exchange server, and now dialup networking users can not access their email. I have tried using outlook set to SMTP and pop3, outlook express set to pop3 and even web access. On outlook it will just sit there at the splash screen and never do anything. On express it will timeout after 1 minute but it sees how many emails are on the server but just sits at the 'download 1 or 13' message until it times out. I have reinstalled Exchange 2000, sp3, and the post sp3 rollup, and still the same thing. I am at my wits end, any help would be greatly appreciated. TIA.
