Hi,
It seems like this is not the first time someone has reported something like
this regarding win64dd/dumpit and large memory samples [1]. If you can, please
try another memory acquisition tool [2] and see if you get the same error. Let
us know what happens.

Hi Bill,
Did you have a chance to reacquire a sample from that machine for comparison?
In the similar issue I linked (issue 401) the person who reported the issue
tried again successfully with Windows Memory Reader which can be found here:
http://cybermarshal.com/index.php/cyber-marshal-utilities/windows-memory-reader
I suspect that your issue is the same as theirs, especially since you are using
the same tool (win64dd and dumpit are from the same author and most likely
contain the same code) and are acquiring the same OS (Win 7 x64 and Win 2008 R2
x64 have the same kernel) both with memory larger than 4GB. Please let us know
if you have any update, otherwise I will just close this issue by the end of
the week. Thanks!

Hello Jamie,
First let me say thank you for your responses..
Yes, I have been able to get an image greater the 8 gig to work by using
Windows Memory Reader and FTK Imager. Thanks for the links
On a side note:
From the testing I have been doing with these 2 images, the one made by WMR and
the one from FTK I have not been able to get the netscan command to show me
anything other the field headers. I am running the following command:
volatility-2.2.standalone.exe --profile=Win2008R2SP1x64 -f memimage.dmp
netscan
FYI - I have let this run on both images for 1 hour then I just killed the
command. (I was waiting to see if 2.3 had better luck with the netscan command)
Am I doing anything wrong, could it still be the images, as I see the command
should work for version 2.2?
Thanks again for your help,
Bill

Hi Bill,
Does psscan work for the two images on which netscan failed?
Also, could you send me the c:\windows\system32\drivers\tcpip.sys file from the
machine's disk (if don't have access to the disk, you can use volatility's
moddump plugin to pull it from memory).
If psscan works and netscan doesn't then there's no issue with the scanning
infrastructure per se, just the signatures or structures we use for network
info...and tcpip.sys is what I need to verify.
I know some people have used Win2008R2SP1x64 with netscan before with success,
so it also could be your memory image...but we'll see.

Hello Michael,
Here is what I did for testing. I ran PSSCAN on both images and it returned
nothing but the field headers (I am able to run PSTREE,PSLIST, DLLLIST,
HANDLES, GETSIDS, ENVARS, DRIVERSCAN to name some of them) So, I decided to
take another image using the two utilities to see if the images were bad since
I was not able to run PSSCAN.
FTK reimage
Running PSSCAN I was able to obtain information rather quickly
Running NETSCAN I was able to obtain information rather quickly
Windows Memory Reader reimage (command: wmr.exe c:\image.dmp)
Running PSSCAN I was able to start pulling information after about 10
minutes of running but was getting about 1 entry (row) every 3 to 4 minutes. Very slow
Running NETSCAN I was able to start pulling information after about 14 minutes of running but was getting about 1 entry (row) every 5 to 10 minutes. Super slow
This has been running for 25 minutes and I have only 2 IPv4 and IPv6 addresses showing
I am not sure why the other 2 images from this same server have issues but I
guess I will just take 2 images using FTK Imager (since it appears to return
faster results)
If you would still like the tcpip.sys I can upload it for you
Thanks for all the help!
If I can be of assistance for anything please let me know
Thanks,
Bill
