i have 4 latops configured exactly the same, 3 of wich are working fine. we have a sonicwall firewall and vpn client. all of the laptops connects via the vpn client which is not a problem, but 1 of the laptops when i open outlook once connected sits on trying to connect for ages but eventually connects after about 10 minutes where as the other 3 laptops work fine and connect with inside a minute or so. what would be the best way to diagnose this problem? i have added our server name and ip address to the hosts file on the laptop. when connected internally all 4 laptops work seamlesley. the laptops are using windows xp pro and office 2003, the server is running sbs2003 premium edition.
