Outlooks resolvers do not resolve.


I am having a rather peculiar issue with outlook.  I have a remote user, using a Cisco VPN client with Transparent Tunneling enabled that’s allowing IPSec over UDP.  She can connect into the network just fine as well as browse intranets, view internal shares, and practically do any thing but view email.  The strange thing if I go into the services of outlook and go to the properties of the Microsoft Exchange Server under the general tab the name of the server is there but not grayed out.  If I then put in the IP address of the server the IP address then resolves to the net bios name, her name then underlines and she is working just fine.  The user is having this problem every other day.  What can I do to fix this issue permanently?

Thanks for the help!

Add the short name (netbios name) and IP address in
C:......\system32\drivers\etc\hosts netbiosname
The netbios name of your exchange server is not known when connecting through VPN (DNS problem or Firewall configuration)
