Dear customer: Since your issue is about Active Directory architecture design, which is out of our support boundary. We advices you to post the issue into the following forum, maybe you can get more help in there. TechNet Forums Windows Server 2008 http://forums.microsoft.com/TechNet/default.aspx?ForumGroupID=161&SiteID=17 Moreover, I also would like provide some basic information for your reference. Yes, you can achieve data sync between your main office and branch office via Microsoft Windows server 2000 or 2003 directory service. Since I didnt know how you connect your main office and branch office, it hard to say whether you should use a router or not. General, router is used to connect two subnets which subnet masks are different. For more information about Active Directory design, you can refer to the following documents: Active Directory Architecture http://technet.microsoft.com/en-us/library/bb727030.aspx Active Directory All Chapters Download http://www.microsoft.com/downloads/details.aspx?FamilyID=9a4c7ac3-185e-4644-9e98-4876b2a477e7&DisplayLang=en Hope this helps.
