[K12OSN] machine attributes get changed after server reset

["ml bortal de" <ml bortal de>]

Hello List,

i am using Ubuntu Server 6.06 with the smbldap installer script from 
majen.net/smbldap/
I use VMWare to run my test systems (Ubuntu server and Windows Domain 
Clients)

After producing a power supply failure (stopping my Ubuntu and windows  
client by the stop button in vmware) and starting them up again i can  
see a delta/change in my ldap database:


Before Power failure:
----------------------
uidNumber: 10000
sambaSID: S-1-5-21-2308582080-1758763575-3976210704-21000    
sambaPwdCanChange: 1201212116
sambaNTPassword: C880093E1682DA079892FF7FF2AEA911
sambaPwdLastSet: 1201212116

After Power failure:
----------------------
uidNumber: 10005
sambaSID: S-1-5-21-2308582080-1758763575-3976210704-21010
sambaPwdCanChange: 1201260229
sambaNTPassword: 2446CE7E7D8B196756E40E80B5EC3A13
sambaPwdLastSet: 1201260229



I did not manually change those properties and i wonder who or why they  
changed.

The result is that my windows client can not log into the domain  
anymore. I have to remove it fro the domain and add it again.

Has anyone an idea why this is _automatically_ happening?
Why, who or what can change those machine attributes?
Do you need more infos?

Thanks, Mario
