After making some amendements to our filter exceptions using filtcfg,
BM server console showed the following :-

RemoveValue failed with error -602
NDSISearchObject failed with error :-6001
NDSIFindPacketFilter failed with ecode:-6001

When I went back into filtcfg the changes had not taken effect....

NDS health check appears O.K....

Help.... Why has this started to happen, moreover, how do I fix
