Hi,
We have multiple AD servers exits in china and singapore. Each country have multiple AD in diff subnet. Currently the AD site configuration is simple , everthing are in default sites and no subnet was configure . The root AD and exchange servers are in singapore and same subnet.
So my question is :
1)what is the best pratice that to configure the AD sites so that the exchange server will have better perfomance ? Currently the AD replication is fast but for exchange sometimes users will experience slowness when they are connecting to china GC which give low latency.
2)I tried to create one more sites and move all the china DC to the new sites , however i keep receiving topology error 2142 &2501(Topology failed to discover. Any reason ?

For a global AD environment the best thing you can do is have sites created based on either the Region or the physical Site.This will prevent Exchange from using a GC outside of that region.An Exchagne server in China should not be using a DC in singapore for lookups and visa versa.
Best bet would be to create a new site, assign subnets to that site and let AD reassign the objects.Make sure you set up site links so that replication can occur properly.I would set up the interval to 15 minutes to keep AD up to date as much as possible.The default setting is 180 minutes.

Hi,
To create the AD sites, the best practice is based on the Regional or Physical locations.
For the error message, please try to use DCdiag/Netdiag to check if we have network or DC connection> Thanks
