Hi Steven,

Please check if the server is selected to allow to Extend the Schema.

1. Click Start, point to Programs, point to Administrative Tools, and then
click Schema Manager.

2. Right-click Active Directory Schema, and then click Operations Master.

3. Click "The Schema may be modified on this domain controller".

Reboot computer and try to run ADprep again.

If the problem still persists, please try the following command to re-acl
the schema.

dsacls CN=Schema,CN=Configuration,DC=domain,DC=com /I:T /G "domain\schema
admins":RPWPWOCCLCWSWPRPLOCA

If you still cannot run ADprep /forestprep, please search the ldif.err,
schupgr.log, ldif.log, schupgr.log files and attach them in your post.

Thank you,
