I hav an issue with NDPS on my NW6.5sp5 server.
The manager is reporting BAD and the latest NDS Events file reads:

Error (-672) was returned, operation "Get Effective Rights",
Replica on Server '#####', Object Name: ######.#### (NDS Interface). This event happens twice a minute in the log file.

I have been searching around for a fix to no avail. This is not my strong area.
Any help is appreciated.
Thank You
