if you use active directory you may notice windows xp sometimes allows you to login to computer even if your network is unplugged. this is because microsoft save your active directory password hash into your system registry using some algorithm named as MSCASH . there are many tools availble on internet to dump or to get these password hashes from registry.Password hash is saved in the Windows registry and by default saved 10 hashes.you can read more about mscash here .

now as you have your lost password hash you can use john the ripper with a small patch to crack your lost password mscash hash.

first you need a linux (ubuntu will be ok ) machine to use john. offcourse u can use windows but i will preffer linux as i dont know how we can patch john for mscash support ( i think you can do it using cygwin ). ok lets download and install john and patch it.

Rule # 1 : Don’t install john using apt-get install john ( if u do have thats ok but we will not be using that ) .

Step # 1 : login to your linux box.

Step # 2: download john 1.72 using :

wget -c ftp://ftp.openwall.com/pub/projects/john/1.7.2/john-1.7.2.tar.gz

Step # 3: extract john using :

tar xzf john-1.7.2.tar.gz

Step # 4: download patch for mscash using :

wget http://coast.cs.purdue.edu/pub/tools/unix/pwdutils/john/contrib/john-1.7.2-mscash-alainesp-4.1.diff.gz

Step # 5: Rename john to :

mv john-1.7.2 john-1.7.2.orig

Step # 6: patch john using :

gunzip -c john-1.7.2-mscash-alainesp-4.1.diff.gz | patch -p0

Step # 7: make John the ripper

cd john-1.7.2.orig/src && make linux-x86-mmx (depend on your system architect)
