Windows Account Keeps Locking Out

-

i have user account (windows 2003 native ad) - account keeps locking out.  i have used account lockout , management tools find out there machine causing account lock (see below)
event type:       success audit
event source:    security
event category: account management
event id:           644
date:                05/06/2011
time:                10:30:30
user:                nt authority\system
computer:         win3klmdc01
description:
user account locked out:
            target account name:    steel
            target account id:         swnet\steel
            caller machine name:    11111111
            caller user name:          win3klmdc01$
            caller domain:   swnet
            caller logon id: (0x0,0x3e7)

in each case caller machine name 11111111 resolves 0.7.119.58.
11111111 inaccessible via rdp.  when ping'd there no reply & nobody seems know device used for.   have nbtstat -an against 11111111 & got nothing no mac address work with.  i therefore cannot onto server figure out if service / scheduled task / drive mapping on device has been configured old password credentials.  

has see before?  suggestions appreciated.  thanks.

my guess is, may caused expiration. attempt rdp not show warning, need change password. disable user, change expiration without limits , enable user. 

regards
