I have an 2003 domain, and i added a new Server 2008 DC (i ran ADprep) and it joined successfully and is replicating. However i noticed on the new DC it's missing the netlogon and sysvol shares and had another error. It threw this error in dcdiag:
Starting test: NetLogons
Unable to connect to the NETLOGON share! (\\server\netlogon)
[server] An net use or LsaPolicy operation failed with error 67,
The network name cannot be found..
......................... server failed test NetLogons

Warning: DsGetDcName returned information for
