I am in the middle of a Server Migration from an SBS2011 Server to a Windows Server 2019. During the step of running ADPREP.EXE /ForestPrep I am encountering the following error:
C:\ADPrep\adprep>adprep /forestprep
ADPREP WARNING:
Before running adprep, all Windows Active Directory Domain Controllers in the fo
rest must run Windows Server 2003 or later.
You are about to upgrade the schema for the Active Directory forest named 'contoso.local', using the Active Directory domain controller (schema master) 'S
BS1.contoso.local'.
This operation cannot be reversed after it completes.
[User Action]
If all domain controllers in the forest run Windows Server 2003 or later and you
want to upgrade the schema, confirm by typing 'C' and then press ENTER to conti
nue. Otherwise, type any other key and press ENTER to quit.

Adprep was unable to create the object CN=Claims Configuration,CN=Services,CN=Co
nfiguration,DC=contoso,DC=local in Active Directory Domain Services.

This Adprep operation failed.

Check the log file ADPrep.log in the C:\Windows\debug\adprep\logs\20201025141729
directory for more information. Restart Adprep.
Adprep encountered an LDAP error.

Att 20119 (nTSecurityDescriptor)
Adprep was unable to update forest information.
[Status/Consequence]
Adprep requires access to existing forest-wide information from the schema master
in order to complete this operation.
[User Action]
Check the log file, ADPrep.log, in the C:\Windows\debug\adprep\logs\20201025141729 directory for more information.
The network has only a single Domain Controller SBS1 and it holds all FSMO Roles, I also migrated from FRS to DFSR for the SysVol. Does someone know what the issue is? The user used for the preparation is a group member of the Enterprise Admins Group and Schema Admins Group as well as Domain Administrators. What Am I missing?
