How can I get domain replication over the internet? I need it so I can have a domain controller in Birmingham, and one in London? I havent really explored the posibility of VPN, but the problem is my upload speed of the site in London is incredibly slow... In Birmingham, the site is fibre optic so we get 40mb download and 10mb upload, but in London we get 3mb download and .5mb upload... Is there anyway to retain performance, and have them replicating? Thanks, Ben

You can use VPN connections for AD replication. Have a look to these Microsoft article about AD replication: http://technet.microsoft.com/en-us/library/cc775549(WS.10).aspx http://technet.microsoft.com/fr-ch/library/cc755994(v=WS.10).aspx For slow link, I recommand the use of Asynchronous replication over SMTP. For replication over firewalls, refer to this Microsoft article: http://technet.microsoft.com/en-us/library/bb727063.aspx This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Hello, create a VPN or use router connections with public ports you have to get from your ISP of course connected over firewalls. http://technet.microsoft.com/en-us/library/dd772723(WS.10).aspx http://technet.microsoft.com/en-us/library/bb125069(EXCHG.65).aspxBest regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

How do you set up Asynchronous replication over SMTP? Do you have any idea of any websites that will help me? I have no idea where to start with this! Thanks

SMTP? While SMTP is an option as an Inter-site transport protocol, I am curious if anyone out there has actually done this in production and can provide their experience.Visit: anITKB.com, an IT Knowledge Base.

Hello, with 512KB as the slowest link in your network prepare the site DC in the main location and ship it then to the new site. That way the major database is already repicated and only changes after relocation has to be done, which is not that amount of data. For a company earning money at least a 2Mbit line shouldn't be a problem to get and then you can easy use VPN connections or a routed network. Do not play around with SMTP replication. this can only the last option. "The SMTP transport has some restrictions: It can be used to replicate configuration and global catalog information, but cannot be used for replication between domain controllers that belong to the same domain and therefore have to replicate the full domain-naming context. The reason for this restriction is that some domain operations (for example: global policy) require the support of the file replication service (FRS) that does not yet support an asynchronous transport like SMTP for replication."
