Dear All, I'm having a problem routing my Exchange Server. The situation is that we have two networks connected thru VPN and both have Gateway/Firewall on each end. The main server is designed as Parent Domain Controller and the other one (on the other network) is promoted as a Child Domain Controller. However, I cannot have to two to be able to receive mails from the Exchange Server. I hope I can make sense to you all about my issue. Your help would be much appreciated and hope to receiving your answer soon. Thanks.
