IOCTL?

NTFSD

Hi,

Can anyone tell me what the IOCTL 0x1404B is, or point me in the right
direction? I’m seeing it in Filemon while monitoring the SMBMRX redirector,
and using office files (word, excel, etc.) on a share.

Thanks,
Matt

Not very sure, but might be generated by the device FILE_DEVICE_BEEP.
Ofcourse I might be totally wrong.

Is the IOCTL value correctly written ?
I doubt that you will see an IOCTL belonging to FILE_DEVICE_BEEP
while monitoring network redirector.

Oops, sorry, it’s 0x14104B. Anyway, the device is
FILE_DEVICE_NETWORK_FILE_SYSTEM, so that makes sense, but I don’t know what
the individual code means.

Here’s the output from ioctl_decoder utility I found sometime back on
the net
IOCTL_CSC_IS_SERVER_OFFLINE
DeviceType=FILE_DEVICE_NETWORK_FILE_SYSTEM, Access=0, Function=1042
Method=METHOD_NEITHER

IOCTL_CSC_IS_SERVER_OFFLINE. Although I don’t exactly know
what this IOCTL means, it is related to the offline folders (CSC is the
old planned name - Client Side Caching).
