Changing users in XP

[Comptech]

I wanted to change the user name and password on a computer that is in a workgroup. When I change the name and password it loses the access to shared drives. How can I change the name and passowrd and still have access to what the user used to have. The only thing I need to do is change the name of the staff name...new staff
Thanks

Did you change the permisions on the shared folders?
