on the computer that I was trying to access, go to
Right Click Start
-->Computer Management
--->Local Users and Groups
--->Users
Within that folder you will see a list of accounts. The one with an down facing arrow suggests that it is disabled so you'll have to enable it for the account you want to give network access to.
