I dont think this is a Hardware Problem. We have this Problem with a VM and a physical Machine. Same issue is descriped here:
Server 2012 R2 File Server Stops Responding to SMB Connections
We have the same issue with 2012:
- Virtual Machine or Physical Machine doesnt matter
- Sometimes Fileshares response slow -> later Shares are inaccessable / do not respond completly
- Installed all Windows Updates
- RDP is possible / no Errors in Eventlogs
- we are able to access files on the local machine
- Reboot fixes the Issue temporäry
Is this also happening with 2012 R2?
