EXCHANGE REPLICATION PROBLEM...
Posted on 2006-06-10
Experts; we are facing a problem with our Exchange Infrastructure; we have 3 Windows 2003 Active Directory Domains in 3 different cities [i.e. city A, city B & city C];
-- city A consisting the abc.com Root Domain
-- city B consisting the def.abc.com Child Domain
-- city C consisting the ghi.abc.com Child Domain
all of them Inter-linked to each other in one forest each domain having;
-- 1 Domain Controller
-- 1 Exchange Server
Now the problem is not actually in the configuration of either the ADS or the Exchange; these cities are inter-connected through Wireless based WAN links & these links are not stable most of the times due to which the Active Directory Replication & the Exchange Replication mostly fails & this causes the emails to hang in the queues especially for the exchange server in the abc.com domain; due to which 9 out of 10 times we have to restart the server in order to push the mails in the queues.
My questions are the following;
1 - How can I customize the replication in such a way that even if the WAN links are not stable the emails should not stop in the queues ?
2- How can I know the replication dependencies for the exchange server for abc.com ?
3- In the scenario that I have described; what is the best practice that we can implement in order to be sure of maximum UP time for the email flow ?
Kindly provide me with a detailed solution to my problem.
