Symptoms
While a client is writing a file to a server across the network, they may receive the following error message:

Windows was unable to save all the data for the file x.
The data has been lost.

The event contains the same text as the error message, but also contains the error status in the data section. Double-click the event, and then click Words for the data type; the last word contains the status. If the status code is c0000022 (which translates to STATUS_ACCESS_DENIED), apply the hotfix that is described in this article. Windows was unable to save all the data for the file x.
The data has been lost.
This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere.
