We sometime need to disjoin/rejoin our computer account to make it work again.
This is because trust relationship between client and server has been broken thus the server cannot authenticate login process from client.
I test following script and it work fine without I have to disjoint/ rejoin computer name.
The format is :
netdom.exe resetpwd /s: /ud: /pd:*
Login as administrator, on command prompt do command above.
