Event message 2
Event Type: Information
Event Source: Application Popup
Event ID: 26
Description:
Application popup: Windows - Delayed Write Failed : Windows was unable to save all the data for the file \\ServerName\VolumeMountPointName\FileName. This data has been lost. This error may be cause by a failure on your computer hardware or network connection. Please try to save this file elsewhere.
CAUSE
This problem occurs when the program writes to a volume mount point that is located on a storage area network (SAN) that is connected by using a Universal Naming Convention (UNC) connection.
Note This problem does not occur when the program writes to a volume that is connected by using a drive letter mapping.
This problem occurs because data transfers from the client to the server do not progress. Subsequently, Windows disconnects from the volume mount point. Therefore, Windows cannot write to the volume mount point.
