This issue was originally reported in MSKB Article 281345 (http://support.microsoft.com/default.aspx?scid=kb;en-us;281345) in reference to an issue with SQL Server.
We recently discovered that SQL Server is not the only source of this issue. Not only is the dialog an annoyance, itís also modal, causing Windows Explorer to pause until the message is acknowledged. Following this tip, you will cause the error dialog to go away and, instead, log the error to the System Event Log.
In our case, some process called CSRSS.EXE (Microsoft Client Server Subsystem) and it attempted to locate media which simply didnít exist. This was revealed to us by running Process Explorer from Sysinternals (http://www.sysinternals.com).
To workaround the problem we did employ Microsoftís registry hack. Click Start, then Run and type regedit. Click OK.
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Windows\ and change the value of the ErrorMode key to 2.
Since this key is queried any time a hard error is received, there is no need to reboot. Obviously, itís best to make this change only after all other efforts to identify the problem have failed.
