Microsoft Windows NT/2000/XP passwords are encrypted as 32-bit one-way hashes using the MD4 messages digest algorithm. This is similar to the way that Unix stores passwords, although the hashing algorithm is different. For compatibility with legacy Microsoft LAN Manager software, Windows NT/2000/XP also stores the passwords redundantly as a 56-bit DES (Data Encryption Standard) hash. This 56-bit hash is created by splitting the password into two 7-character uppercase strings, and then converting each to a 56-bit DES key which both then encrypt the string “KGS!@#$%” and concatenating the results. This Read More

The Limitations of the Windows NT Domain Model and Network Security With Windows NT, domains were utilized to manage users, and to manage and secure network resources. A domain is the logical grouping of servers and network resources under a single domain name. In Windows NT, a domain could be considered as a central database containing security information which was then basically used to manage users and network resources. The Windows NT computers operated as domain controllers, with each domain essentially having one Primary Domain Controller (PDC) and one or Read More
