Hello, I have now checked, Event ID 4004 Error 9003 .
Can this fault be resolved only by deleting the DFSR Database in System Volume Information?

Absolutely not. The simplest solution may be to demote, reboot, promo the problematic one. Also how long has this been going on? If this exceeds the tombstone life then this one should be removed from network, seize roles (if necessary)

Transfer or seize FSMO roles - Windows Server | Microsoft Learn

then do clean up

Clean up AD DS server metadata | Microsoft Learn

and rebuild the failed one.

By deleting the DFS database in System Volume Information in Driver C, and letting it rebuild automatically. Fixed this issue. Thanks a lot.
