Hi,
One of my customer has a AD forest which contains three domains. It has root domain and two child domains. We are having problems with only one child domain and parent domain. Replication failed in between these two domains. Root domain installed on Server 2012 R2 and child domain on Server 2008 R2.
Customer said that this issue occurred just after deleting the Parent-Child trust between the domains. This was done by some engineer from a different company to overcome an issue while he was installing a service pack for Exchange 2010. Anyway the deletion performed by using ADSIEdit. After deleting the parent-child trust, Exchange setup was successful and he created the trust again but it was a External and non-transitive trust. According to the customer, this can be true as well.
Now, replication between the parent and child domain doesn't occur and there are so many errors if I mention. If I am stating few commonly noticeable issues are:
- "NTDS Settings" object is missing in the AD Sites and Services console (Parent domain side)
- "NTDS Settings" object is present in the AD Sites and Services console (Child domain side) and once I select the "Replicate Now" option it gave me an "Access Denied" Error.
So, Please be kind enough to let me know a solution for this issue.
Regards,
Thisaru Perera.
