DFS Replication: Corrupt Database - Event ID 467

DFS not replicating with the following event logged on the affected server:

DFSRs (1624) \\.\F:\System Volume Information\DFSR\database_123A_B9CD_8EF9_4623\dfsr.db: Database \\.\F:\System Volume Information\DFSR\database_123A_B9CD_8EF9_4623\dfsr.db: Index IDContentSetIdGvsnIndex of table IDTable is corrupted (0).

To resolve:

Backup replicated DFS directory using Robocopy:

robocopy F:\ G:\ /B /E /COPYALL /DCOPY:T /R:6 /XD "$RECYCLE.BIN" "System Volume Information" /LOG:robo.log /TEE

Run secondary backup if necessary using /PURGE to mirror any subsequent changes:

robocopy F:\ G:\ /B /E /COPYALL /DCOPY:T /R:6 /XD "$RECYCLE.BIN" "System Volume Information" /LOG:robo.log /TEE /PURGE

Open command prompt, change to affected drive and run dir to obtain file list for future reference:

dir /B /S > c:\filelist.txt

Delete replication groups and members and stop DFSR service on server with corrupt database:

net stop DFSR

Launch elevated command prompt and grant Domains Admins right to the System Volume Information folder on affected DFSR drive:

icacls "F:\System Volume Information" /Grant "Domain Admins":F

Delete corrupt DFSR directory within System Volume Information:
 
rd "F:\System Volume Information\DFSR" /S /Q

Remove Domain Admins from System Volume Information:

icacls "F:\System Volume Information" /remove:g "Domain Admins"

Restart DFSR service and recreate replication group.

Monitor the status of DFS replication:

wmic /namespace:\\root\microsoftdfs path dfsrreplicatedfolderinfo get replicationgroupname,replicatedfoldername,state

dfsrdiag replicationstate
