I have a 2000 forest and domain that I need to move to 2012. First I have to move to 2003.
When I run Adprep /forestprep on the 2000 DC, Adprep fails with “Adprep was unable to extend the schema. The schema master did not complete a replication cycle after the last reboot.”
However, I have one and only one domain controller, it doesn’t replicate anywhere. I have no BDC or secondary DC. Why would I be getting this message and how can I correct this ?
