Thanks for taking the time to post. I just returned from yet another trip to unplug the EX4100 and restart it. Only ran for a day this time after I turned off all Internet access completely. So that was my last resort. If you look at this thread you’ll see all the time I’ve put in troubleshooting.
The desktop PC you mention with the WD View app installed, is it on the same network as the EX4100 at your place of work? I assume that it is, as I think you are saying that web access is turned off.
I’ll need to check if I installed that app on the PC that backs up to the EX4100. It is running the WD Smartware backup application and so should see some activity almost every day. In addition the EX4100 is set to power down every night.
My EX4100 recently ran 11 days without a lockup, but that’s the exception. It often has to be restarted every two or three days, and sometimes locks up within a few hours.
Anyway, thanks for the input. Something to think about at least.
