Logging unto Computer

[Bazile]

On my home computer there is a username for myself and my daughter .

My daughter has a password to enter when she clicks unto her username
I have never had a password - i simply clicked unto my username and was able to get unto the system .

Now all of a sudden , when my daughter tries to get unto the system - after entering her password , a message comes up stating that ' the system cannot log you on now because the domain
YOUR-BY3NR533HT is not available '

Also when i click unto my username , it's asking for a password - even though I have never had a password on my username .

We have Windows XP

Does anyone have any ideas as to what's gone wrong .
Any help would be greatly appreciated as to how we can get unto the system

Sounds like you have XP PRO (rather than home) and it is trying to log you on to the domain rather than the PC. When you get to the login screen are there boxes for "User name" and "Password"? If so, there should be a third box for "Log on to" - you may need to press "Options" to see this. Use the arrow at the end of the "Log on to" box to change to the other option. From memory - no time to reboot a PC to check - it will be something like NAME (This computer). If you can get logged on OK, next time you reboot hide the third box by pressing "Options" again.
