I am trying to switch on the roll forward log using DSBK (dsbk.dlm) utility in windows server 2008.
However I am seeing the error in output file as:

Command line setconfig -L -r E:\Backup

Processing command line
DSBsetConfig err = -663

Setconfig initiated.
It will take some time!!!DSBK error! -663

Can someone kindly guide me on this error and how to resolve it.
