SYMPTOMS
When you attempt to transfer large amounts of data or install a disk I/O intensive application through the network, the following system event appears in the Event Viewer:

Event ID: 26

Description: System Process - Lost Delayed-Write Data : The system was attempting to transfer file data from buffers to.



CAUSE
This problem occurs due to a defective network hardware, such as a hub or cable.



RESOLUTION
To troubleshoot this behavior:
 * 1) Copy another file through the network (preferably between two computers in close proximity) and check the Event Viewer.
 * 2) Connect the two computers to the same hub. Copy the file again.
 * 3) If you have enough hard disk space, install the disk I/O intensive application directly on the Windows NT Server, instead of over the network.
 * 4) Disable any "filter" drivers, such as quota management, anti-virus, or open-file software.

If Event ID 26 appears again in step 1 and the file transfer fails in step 2 and the installation in step 3 completes successfully, replace the hub and cable, and repeat the steps above.
