Persistent network error on single file

I have a problem which started yesterday at two completly unrelated clients.

Both are ruing an application on a terminal server 2012 from a network share.

When starting the application they now get an error message "error performing inpage operation".
Process monitor shows a "network error"

IRP_MJ_READ \serverapplication.exe
NETWORK ERROR Offset: 413,696, Length: 15,872, I/O Flags: Non-cached, Paging I/O, Synchronous Paging I/O, Priority: Normal

(offset and length are within the file size)

The error is repeatable and happen for all user on the terminal server. A few other applications on the share show the same error while others work fine. All applications runs fine on the server.

The first client does not have inteet access from the terminal server nor application server and AFAIK no updates has been applied recently. Not sure of the status of the second client.

Restarting the terminal server solved the problem for the second client. Currently waiting for a service window for the first client.

Any ideas what might have happened?
