The KXRPC service not running will not prevent you from starting a KiXtart script but you will not be able to use certain Kixtart functions. Therefore, it is recommended to run the KXRPC service on all domain controllers.

Also, make sure the following files are in the NETLOGON folder of all domain controllers (maybe even enable directory replication):
KIX32.EXE
KX16.DLL
KX32.DLL
KX95.DLL
LOGON.BAT
LOGON.KIX

Then try again.
