Urgent : Windows Error 995 using MySQL+InnoDb 4.0.17 on W2000

[yawi]

Hi all,

Today, I've obtained the following error several
times :
MYSQL stops with the Windows error number 995 ("The
I/O operation has been aborted because of either a
read exit or an application request.&quot

------------------------------------------------------
040131 19:11:47 InnoDB: Started
MySQL: ready for connections.
Version: '4.0.17-nt-log' socket: '' port: 3306
040131 20:06:45 InnoDB: Operating system error number
995 in a file operation.
InnoDB: See

InnoDB: about operating system error numbers.
InnoDB: File name e:\mysql_data\ibdata1
InnoDB: File operation call: 'Windows aio'.
InnoDB: Cannot continue operation.
040131 20:06:54 InnoDB: Database was not shut down
normally.
InnoDB: Starting recovery from log files...
------------------------------------------------------


Err file says that involved file is an InnoDb data
file. It happens sometimes with my file1, sometimes
with my file2.

In fact, I have this trouble since I changed my
hardware..(always on W2000 but with patch 2 on my old
server, with patch 4 on my new on).


Can someone help me ?
Thanks&Regards
