Windows Network Block Device Server
2012 Jeff Bryner
A DFIR/forensic take on nbdsrvr by Folkert van Heusden (

Modified to 
1) allow you to specify a whitelist IP address that can connect to the NBD Server
2) defaults to read only access to the partition
3) provide access to disk or memory
3) provide optional debug messages
4) compiles via mingw on windows

.exe provided here is 32 bit, and runs on winxp, win7, win2008.

Video Demo:

NBDServer.exe v3.0
 -c     Client IP address to accept connections from
 -p     Port to listen on (60000 by default)
 -f     File to serve ( \\.\PHYSICALDRIVE0 or \\.\pmem for example)
 -n     Partition on disk to serve (0 if not specified)
 -w     Enable writing (disabled by default)
 -d     Enable debug messages
 -q     Be messages
 -h     This help text

 -f option supports names like the following: 
  \\.\PHYSICALDRIVE0    raw drive partition access along with -n option
  \\.\C:                volume access (no need for -n option)
  \\.\HarddiskVolume1   volume access (no need for -n option)
  afile.dd              serve up the contents of 'afile.dd' via nbd.
  \\.\pmem              access the pmem memory driver from volatility
