Single SBS 2003 server in small domain, obviously holding all FSMO roles, DNS, DHCP, File and Print, is not using any of the functionality of SBS, i.e. SQL or Exchange. I’ve tried to install and migrate it to a Server 2008 standard. ADPREP /forestprep and ADPREP /domainprep all ran successfully, Server 2008 is joined to SBS 2003 domain but when attempting to dcpromo Server 2008 into SBS 2003 domain, all go well until trying to replicate the schema. It shows the following error:
The operation failed because:
Active Directory Domain Services could not replicate the directory partition CN=Schema,CN=Configuration,DC=domain,DC=local from the remote Active Directory Domain Controller Server.domain.local.
"The source server is currently rejecting replication requests."
I have taken the following attempts to solve it:
1. Setting schema permissions for Domain Administrator (the account I am doing the dcpromo as) to the same as the Schema Admin Group.
2. Editing registry HKLM/System/CurrentControlSet/Services/NTDS/Parameters "Schema Update Allowed" to value of 1
3. Raising forest and domain functional level to Server 2003 native.
4. Disabling broadComm NIC on Server 2008 as I didn’t need it due to the dual Intel card.
Can anyone provide me with any help, please?
