SYMPTOMS

While a client is writing a file to a server across the network, they may receive the following error message:
{Delayed Write Failed}
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.
To determine whether the client is experiencing the problem that is described in this article, check the event log. The event log must contain event ID 50 with a source of MrxSMB. 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.

CAUSE

This problem occurs because the client redirector does not calculate the SMB signature properly.

Note Apply the patch to the computer that is receiving the Delayed Write error message, the client computer.
