Hi,
I am also having the same problem, this problem started showing when migration of DP 7.03 from windows 32-bit to 64-bit windows server 2008 did not go well so I revert it back to the old CM by restoring the IDB.
I also run the command omnidbutil -change_cell_name to the old host but the cell name still shows the New Server name i.e windows 64 bit machine name but not the old one.
Could anyone please give solution for this
