Here is the situation:
Single SBS 2003 server in small domain, obviously holding all FSMO roles, DNS, DHCP, File and Print. They are NOT using any of the functionality of SBS, i.e. SQL or Exchange. Trying to install and migrate to a Server 2008 standard. ADPREP /forestprep and ADPREP /domainprep all ran successfully. Server 2008 is joined to SBS 2003 domain. When attempting to dcpromo Server 2008 into SBS 2003 domain, all goes well until trying to replicate the schema.
Error is as follows:
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."
Things I have tried...
1. Setting schema permissions for Domain Administrator (the account I am doing the dcpromo as) to the same as the Schema Admins group
2. Edit registry HKLM/System/CurrentControlSet/Services/NTDS/Parameters "Schema Update Allowed" to value of 1
3. Raised forest and domain functional level to Server 2003 native.
4. Disabled BroadComm NIC on Server 2008 as I didnt need it due to the dual Intel card.
Can anyone provide any help??
