Hi! I want to impletment AD for each branch in the single forest and i want to install the exchange server 2007 for each branch and make the clustering from Exchange at the branch to HQ? What do you think if I install Exchange cluster for each branches, and what is the advantage or disavantage of this point?

Is there a business/technical reason for implementing an Exchange server in every branch office? Most companies are trying to consolidate Exchange servers more centrally. This provides lower cost and complexity. If you do want to deploy Exchange 2007 in a branch and wanting to "cluster", then really your only choice with Exch 2007 is SCR. Note this isn't an automatic failover configuration if that is what you are striving for. I guess my main question is, what are you trying to accomplish with this train of thought? Once you define that, then a solution can be crafted.

Hi Thanks for your recommandation, for me I think that no need to implement it and i will apply OWA for cleint at the branch connect to HQ. and I have one problem relate to as bellow: Source: MSExchangeTransport Category: TransportService Event ID: 12014 Microsoft Exchange couldn't find a certificate that contains the domain name mail.mydomian.com in the personal store on the local computer. Therefore, it is unable to offer the STARTTLS SMTP verb for any connector with a FQDN parameter of mail.mydomain.com. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for every connector FQDN. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. How can fix this ? the problem from my Certificate or my exchange server 2007?

Hi, You can still use Outlook from the branch offices (use Outlook anywhere if the link i sslow). The error message just says that there is a name missing on the certificate used for SMTP. It is just a warning message - message flow should still work. Leif

hi Yes it is working but I don't want to get warning message from that I want to fix it... please help me for this case thank before hand.

Hi, You need to get a new certificate including the current names and adding the missing name. Leif

hi! I still have problem with this issue (the certificate Authentication), ok in my organization i have use the Certifcate Authentication from Domain Controller Start --> Control Panel --> Add/Remove program --> Add/Remove Windows Components --> Certificate Services step1: I open the IIS under Mydomain --> Web site--> right click on Default web site --> Propoties --> Directory Security -->click on Server Certificate --> Assing new certificate. and than i got the new file name Cert.txt and it is store information of my new certificate than i login to my Primary domain by http://mydomain/certsrv --> Request Certificate --> Submit a certificate request by using a base-64-encoded CMC or PKCS #10 file, or submit a renewal request by using a base-64-encoded PKCS #7 file. --> paste the information from my Cert.txt on Saved request --> submit. But it is not work for this case, I hope that you will give me some way to fine the solution for this problem and dose it work with Windows CA or not?
