Whilst trying to retrieve email on a customers machine, the error that the mail host cannot be found is received. All email details are correct, server, user name, password etc. Access to the internet is possible as is browsing the web. Have tried to telnet into mail server to no avail. The mail server is up and running as tested by another machine. Have uninstalled and reinstalled dialup networking. Have uninstalled and reinstalled mail program, still same result. Technet only supply the obvious answers like check connection/password ETC. The mail program being used is Outlook 2000 however the same results are received whilst using Outlook Express which leads me to believe that this problem is not program specific. This one has me baffled, any help would be greatly received.
