Recently the I had a need to add additional systems to a DFS-R group but discovered replication in general was broken. Ran the report and was told this: “A database problem is blocking replication on volume D:” Lucky for me I deal with shitty systems regularly and this was just another Monday. Here’s the 5 lines you need then wait a little bit(maybe a few hours depending on file count) for replication to catch up and go.

• net stop dfsr
• icacls “D:\System Volume Information” /grant “Domain Admins”:F
• cd “D:\System Volume Information”move DFSR D:\DFSR_backup
• icacls “D:\System Volume Information” /remove:g “Domain Admins”
• net start dfsr
