On the endpoint agent channel filter, you are attempting to exclude all shares on a given server from being scanned.
You enter the server FQDN of the server and a wildcard to exclude all shares, but you receive the 'Network share path filter entered is invalid' message in the console and cannot save the path. eg:
\\myservername\*
Release : 15.x
The syntax is incorrect.
You must add a share name and a path to exclude. Both can be wildcards eg:
\\myservername\*\*
