Environment: Exchange 2007 SP3 on Windows 2008 Servers, AD 2008/2003 DC's, multiple AD sites (Tokyo, NY, London, Sydney). A user in NY got married and submitted a request to have her email/display name changed from Jane Doe to Jane Smith. This was carried out in NY on Saturday. I confirmed the change by checking on another NY Exch server I was carrying out some work on. I logged onto a Sydney Exchange server today and the change had not updated. I logged onto a different Sydney Exchange server and the change WAS there. I then checked the Sydney DC's, and some DC's had the new name, others didn't. Looks like we have replication issues, but I wanted to check - 1. When using the Exchange 2007 Management Console (or even the Management Shell), how can I check which DC I'm connected to? 2. If I wanted to check whether there was a replication problem on the DC with the Jane Doe name, would Dcdiag show me this? What should I be looking for? An other, replication specific command I can run? 3. How can I force replication within the same AD site? 4. How can I force replication to a specific AD server from a specific AD server? 5. Is there any ill effect of forcing replication from one server to another? Is there any chance of replicating false data? 6. For an example situation, let me say that the DC with Jane Doe (i.e. had not updated yet) was set to replicate to London. Does this mean that London DC's would also have old data?

HI Neil, You can see EVnt Id : 2138 for Source: MSExchange ADAccess to determine which DC is connected thru. DCDiag will help you to determine health of DC not the replication status. YOu ca use Replmon tool to determine if there is any problem ion DC replication. Here, If you see any DC is not replicating data well and you have other DC in same site then you can simply point Exchnage 2007 server to other healthy and troubleshoot problem DC. To point other DC in exchange you can use "Set-ExchnageServer" cmdlet. Set-ExchangeServer "ExchangeServerName" -StaticDomainControllers DC1,DC2,DC3 -StaticGlobalCatalogs GC1,GC2,GC3 http://social.technet.microsoft.com/Forums/en/exchangesvradmin/thread/349ca379-f435-417f-a41a-98fccde450ef Also I will advise you to post a same thred in Active Directry forum for replication issue. http://social.technet.microsoft.com/Forums/en/winserverDS/threadsAnil MCC 2011,ITIL V3,MCSA 2003,MCTS 2010, My Blog : http://messagingschool.wordpress.com

You can navigate to the following place to check which DC is connected. Server Configuration-> Server->Right click server name and select Properties->switch to System Settings tab. To force replication between DCs, you can refer to the following articles: http://technet.microsoft.com/en-us/library/cc770963(WS.10).aspx http://technet.microsoft.com/en-us/library/cc816926(WS.10).aspx Thanks.
