After you run the NTBackup utility (Ntbackup.exe) to fully restore the System State data, network adapters may be missing or have incorrect names in Device Manager. New wide area network (WAN) miniports (Layer 2 Tunneling Protocol [L2TP]) that were not present before you ran the restore operation may now be present. You may not be able to remove the new adaptors that appear in Device Manager and reinstall the missing ones.
This problem occurs because only part of the Plug and Play database is being restored. Therefore, the Plug and Play database is in an inconsistent state.
To restore the System State data in future backups so that devices work properly, follow these steps.
NOTE: You must also apply this change to the Windows 2000 installation that will host the Ntbackup.exe restore process. Backups of System State data that are run before making this change will continue to cause the symptoms that are described in this article.
