Problem:  COMPLETE NETWORK LOCKUP:  
    All workstations freeze;
    Cannot authenticate into any network device until reset;  
    Server (DC) has to be hard powered down to restart.  
    Hard reset on server fixes problem

Notes:

1. Domain Controller is 2003 R2 X64 SP2 with all critical and security patches applied

2. No events are written to log files when lockups occur

3. Server IP (and other devices) can be pinged during lockup

4. Login screen can be accessed on all other servers but if user name and password is entered, the system "locks" up.  (authentication failing)

5. Disk arrays are healthy

6. Network traffic normal during lockup
