TruScan proactive threat scan whitelist will not update
We have a SEPM (11 RU6MP1) that had stopped updating all content a few days ago. Running liveupdate from the SEPM console resulted in failure with 'return code = 4'. I therefore attempted to run LUALL in interactive mode and received a failure (LU1835) stating the server did not respond in a timely fashion. Eventually I discovered that if I deselect TruScan proactive threat scan whitelist WIN32 11.0 and TruScan proactive threat scan whitelist WIN64 11.0 then it would update all the other components.
So now I'm stuck with how to update these two components. Anyone got any ideas?
P.S. There is no Proxy server or firewall
