3 Domain controllers, migrate SYSVOL replication from FRS to DFS but then had to restore PDC to a backup which he was to FRS... now cannot replicate

hello all,

have an issue and i would like some assistance.

i Have 3 domain controllers and i successfully migrated the SYSVOL replication from File Replication Service (FRS) to Distributed File System (DFS Replication) one week ago. 

then when i was trying something else my DHCP broke at the PDC so i had to restore to a backup and the latest backup which i had was prior the nigratoin of SYSVOL. so now i get error messages.

PDC: when i run the command: dfsrmig /getmigrationstate i get the the PDC is in (eliminating) state

when i run the same command from the other two domain controllers i get: "Unable to connect to the PDC emulator. Make sure that the PDC is reachable and retry the command later."

any help would be appreciated.
