our employees are allowed to access the ms exchange server 5.5 via vpn. mail client is outlook 2000. an employee purchased a new pc loaded with windows me and office 2000. she cannot successfully attach to the exchange server via her DSL connection. old pc with win98/outlook 98 connected fine over the same dsl. she brought the new pc to the office, it will connect to server via local ethernet. the variable seems to be the vpn connection. exchange will prompt her for user/pw/domain, but never successfully logs on. any ideas?
