I have a user abroad, who is using Watchguard VPN to connect to a firebox in the UK. The user can ping the Exchange server but when trying to set up Outlook gets the message that the names cannot be resolved. User has tried to connect by using the names : Exchange, DOMAIN\Exchange, 192.168.1.XXX, exchange.domain.com, all with no success. User name is entered in the form DOMAIN\joe.bloggs
Webmail works , though a bit slow, but doesn't have the shared calender functions.
What am I doing wrong here guys ? I'm puzzled, and the remote worker in getting impatient.
