none
same internal and external domain name

    Question

  • hello,
    i currently have a windows 2003 domain environment with the same internal domain as my external domain. I also have exchange 2007 with mail working perfectly fine except for my remote site. I have a dedicated ipsec vpn line to my remote site that is part of my domain. The windows 2003 server that i have on the remote site has active directory integrated zone and i have configured a site link to my main office using active directory sites and services. So my primary network is address 192.168.1.0 and remote is 192.168.2.0. when the vpn link is up an running all mail flows smoothy but the problem arises when the connection drops due to internet problems at the remote site. When the link is down users at the remote site cant get email through outlook or owa. Im pretty sure the reason is because the remote mail clients go through the vpn link to get access to email. I know the root of the problem is because im using the same internal and external domain name. i create an A record on my remote dns server saying anything going to mail.xxx.xxx go to the external ip address and i left the existing A record in place which point to my mail server's internal ip address. i had my brother change that at the remote site but dont know if it will work. Any recommendations on how to fix this? 

    Thanks
