Change domain to local user

Hi All,

I would like to change my old XP Pro computer that was previously configured to a network domain to a local user computer. I read that if I just change or rename it to a separate workgroup, I will not be able to access the computer if the local users are not set-up properly with administrative rights.

I would appreciate it if you could point me in the correct direction. I would hate to be one of those that cannot log in after the change. I am a novice in regards to this set-up. Thanks so much for your attention and help.
