We are running a Dell NX3200 NAS (Windows Storage Server 2012). It has been in operation for a few weeks, but we started having major issues yesterday. Three times in the past 24 hours,but we cannot remote into it via RDC, logmein, etc. Also, all users lose access to their file shares. However, we can ping the server. After a hard reset, services are restored for a while. I don't see anything in the Event Viewer that would indicate what is causing this. Any ideas where to troubleshoot next?
