I have an issue that I'm not really sure how to troubleshoot. I have 4 workstations all connected to an in-house Domain Controller/File Server.
Periodically, maybe 1-2 times per day. The users will be working and then they will go to save whatever they are working on (usually Excel), they get an error basically saying they can't save the file because it can't find the original file. The computer does not disconnect from the internet. I login and find that all of their desktop icons are missing (due to folder redirection), and they have been disconnected from their drive maps.
Their folders in the server are now accumulating .tmp files in the directories they are working in because when they are working on an excel document and get forcibly disconnected it is leaving the temp file. I have verified this by changing the extension of the .tmp file to .xls and excel opens it properly, so the the .tmp files are not ransomware related.
The user reboots the computer and everything is normal again for half a day.
- Computers do not disconnect simultaneously, I only get reports of disconnects from one person at a time at completely different times, completely intermittent and the issue cannot be replicated by the user.
- Server has been rebooted multiple times (Server 2008).
- I have gone out and done a full network reboot, including replacing their switches.
- Nothing has changed for them, the only thing I can think of is maybe a recent Windows update is causing this, has anyone heard of anything? It's so weird that they all experience the same issue all at different times.
