We're experiencing an issue at the moment where files over a certain size fail to upload to a 3rd party server. Anything under 50mb goes through just fine, anything over this fails and a standard McAfee GTI Access Denied message appears. A search of the firewall logs does not reveal any failed loads.
Can anyone think what could be the cause. We have techs on it but they've not found anything et so thought I'd ask here!
Thanks in advance
