RE: [ActiveDir] Site Links

[Bernard, Aric]

To be sure, connection objects and site links are two different things.  Connection objects I typically created by the KCC/ISTG although they can be created manually.  Site Links are always created “manually” even if that manual operation is performed by a script.   Site links should be created to join AD sites, which typically represent physically different locations. From a physical to logical mapping, in most cases, the site link represents the WAN link between those locations.  If bandwidth is at all a concern (throughput or latency) you should in most cases create site link with only two members: the hub site and the specific spoke site.  This provides optimal control and knowledge of what systems connection objects will be created between.  In the unlikely event (hopefully) that all of your hub domain controllers are down for an extended period of time, your spoke site could connect and replicate with other spokes attached to the same hub so long as site link transitivity has not been disabled.  If your spoke sites have direct network access to more than one hub location (via frame cloud or alternate link) then it might be advantageous to implement a secondary higher cost site link in the same manner to act as a backup.   As Mark mentioned, if at all possible, let the KCC/ISTG create and remove the required connection objects as it sees fit.  This is typically the most reliable way of maintaining a connected and properly replicating topology all else being equal (and properly configured :-).     Aric   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Creamer, Mark Sent: Tuesday, February 07, 2006 11:42 AM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] Site Links   Do you have manually created links? You’ll likely get a lot better answers than mine, but basically when I had replication problems, I eventually determined that a lot of it was my own causing. Basically, I had no reason to create any site links manually, which I had done. I got rid of those, changed the costs per recommendations on this list, and let the KCC do the rest. It’s been perfect ever since.   <mc> From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Adeel Ansari Sent: Tuesday, February 07, 2006 2:31 PM To: ActiveDir@mail.activedir.org Subject: [ActiveDir] Site Links   AD Experts,   Is there any best practices for creating and managing site links? The problem I am facing where I have many hub and spoke sites with well over 20 site links. What is the best procedure to fix this issue?   -Adeel This e-mail transmission contains information that is intended to be confidential and privileged.
