Logon Failure: unknown user name or bad password

[Kirst007]

I have a laptop that will logon to the domain controller server with no problems but once it is logged on it cannot connect to network drives that are located on the domain controller (it can however connect to network drives on another server) and states "Logon Failure: unknown user name or bad password". If i log on to a different PC with that username then it can connect to the drives so it appears to be isolated to that machine.
It has done this in the past and i had to create a new user profile but it has now done it again. Any ideas how to resolve this please?

Looks like the system has lost its password sync with the DC's.
