help with a work laptop

[pat2k5]

changed a computer from a domain to a workgroup and now can't logon.

the domain is for a business and now can't get into windows at all not even in safe mode.

is there a way to change it back ??

Are you sure you're not trying to login to the domain account? Because since the laptop is on a workgroup now you have to login locally. Try the build-in administrator account. If this password is changed, you can still reset it, if this account is disable..then you can still re enable it.
