I recently got my laptop repaired by Sony and when it came back it had of course been wiped (despite only have the screen replaced).
When I tried to logon to my WHS shares using the sony OS image that they provided I couldn't. A logon dialogue appeared and when I tried entering my name and password the login window remained but had replaced my name with <computerName>/Firstname
I have now managed to restore my PC from a backup - this took a few attempts as initially I removed the system reserved partition so I then had to return to the sony image then restore again using the sytem reserved partition from the sony OS image.
I now have my laptop restored but I still can't logon to my shares. The connector says that my passworss to do not match but they do! I have changed my password on both server and laptop then changed them back to the original and I am still having problems.
I occassionally get locked out and use these steps to unlock my account:
