My internal W2K3-network is connected with the Internet by a server running Kerio Winroute Firewall.

I have several people that are working with notebooks internal and external. When they are external they can use VPN-client to connect with the office. But they can not reach the Exchange-server. Outlook is configured for internal use: Exchange-server=server3. But via VPN we can not reach the dis-name "server3", only the ip-adres. The problem is that Outlook resolves the ip-adres back to "server3" and we can not connect.

I hope that someone understands me, cause my problem is not verywell discribed. Can someone help me?

I think that my problem is solved when my DNS-servers can resolve the Ip-adres that kerio gives the VPN-clients. How can I establish that?

Easy solution:
If you change the outlook setting to point towards the IP instead of 'server3' you should be ok (since you can reach the servers IP address once connected with VPN).

first sorry my poor english, still keep trying ...

try this:

open dos box (cmd.exe)
goto to the etc directory:
cd %systemroot%\system32\drivers\etc
look for files with "lmhosts" in the filename:
dir lmhosts.*

if there is only the lmosts sample file (lmhosts.sam) copy
this file to a file without extension !
copy lmhosts.sam lmhosts. << note the "." at the end >>

edit the lmhosts.
notepad lmhosts.

now read the example, then insert your configuration, e.g.: #PRE #DOM:maildomain server3

in the above example, line one inserts the fqdn and also instructs windows to preload (#PRE) the name (load before login) and also tells windows (#DOM) that this is a domainmaster of the exampledomain "maildomain"
note that the #PRE and #DOM are optional, but it is important that you use the internal ip Adresses (seen after establishing the vpn tunnel)

line two also associates the netbios name with the internal ip address.

i use this in serveral configurations without any problem

ps: if you have more than one domain / exchange servers you can use multiple lines with the #PRE and/or #DOM statement
