A program may stop responding, and event 50 and event 26 are logged, when the program tries to write data to a volume mount point on a Windows Server 2003-based computer

Symptoms

When a program that is running on a Microsoft Windows Server 2003-based computer tries to write data to a volume mount point, your program may stop responding. The following events are logged to the System log:

Event message 1Event message 2

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.
