2. System status Backup must come from Windows 2003 DCs in the same domain.
3. When backing up, the source DC must be completely normal and use NetDiag. EXE and DCDIAG. EXE Make sure DC has a clean event log and the correct DNS registration, use the repadmin.exe / showrepl / all command to ensure the cleaning replication. Test Virtual Files Make sure that the duplicate file replication service (FRS) is replicated, ensuring that DC can respond to the lightweight directory access protocol (LDAP) query and remote call RPC, make sure DC has Netlogon and sysvol sharing . Finally, make sure the DIT file contains fewer fragments.
