NLSLSP error

I have a NW5(SP5)server that is part of a WAN environment(mixed 5,5.1)that I’m receiving the error below on. This particular server contains a r/w replica of Root and two subordinates.

1-17-2001 1:30:18 pm: SERVER-5.0-0
NLSLSP.NLM:Warning:Unable to write license usage information to NDS. Historical usage information may be incomplete. Check
“[Root]” partition synchronization status.
Service will continue. OB_EAST.EAST_OB

Any ideas? Thanks.
