  • delete all .wallet files and restore from backup to the DFS namespace

    e.g. \\domain.co.uk\sysvol

  • Just finished a cleanup job from a ransomware that infected the SYSVOL of a domain.

    Hopefully you have a backup of the SYSVOL folder, which should be included with a backup of the System State. Assuming you do, you need to stop the File Replication Service (NTFRS) on all but the one DC you're restoring the SYSVOL to. Then, with the NTFRS service still stopped on the other DCs, set their registry to a non-authoritative restore before starting the NTFRS service. That way they'll pull good SYSVOL information from the healthy server.

    For more info on authoritative/non-authoritative SYSVOL restores, see https://support.microsoft.com/en-us/help/290762/using-the-burflags-registry-key-to-reinitialize-file-replication-service
