NOM doesnt give actual Client List

Hi All,

I have NOM installed for NetBackup 6.5.5 version.

I have 5 Master servers, 4 linux and 1 windows

I am having problem in NOM report. I am not receiving accurate report from NOM. I have total of 50 clients servers, 10 for each master server. When i receive the NOM report total client list is around 80 clients.

I have cross verified from each of the master server and the client list is 50. I am not sure why i am getting wrong report from NOM.

Some of the additional servers (apart from actual client list) was managed by some other team they have different master servers. we dont have these servers in the client list at all.

Please help me to understand why and what is causing this discrepancy
