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

Hi,

We have Client Server topology for Symantec Endpoint Protection Server 14.1 

One of the lcient is getting "Reputation check for unproven files failed because of network errors for the last 3 days." the client contains sensitive info and is not connected to the internet. I was reading online that for Reputation Check, you need access to the internet. 

The client has no internet connectivity. What should I do to get rid of this error?

Thanks

Jamshed
