Reputation check problem

Hi everyone,

we have Symantec Endpoint Protection Manager 12.1.6 MP4 installed on a Windows server.

All is working fine except for a notification that keeps arriving by e-mail since 10 days.

Theis notification is about one Windows 7 x64 pc that had some network issues for 2-3 days and then recovered.

Since that days, our Endpoint Protection Manager keeps sending this notification to me (the admin of the server):

Reputation check for unproven files failed because of network errors for the last 3 days

I already told SEP through console to acknowledge this problem, but every day I'm receiving the same e-mail notification.

What should I do, except to disable those notifications (that I don't want to disable, indeed)?

Thanks in advance for your time,

Regards
