Cannot Access Private Share created for User

I’ve created a User and asked the interface to create a User folder, which it has done. However, when I try to access it the username is rejected. What I see is this:

  1. I enter the user name and password

  2. when I press enter the password is rejected and the user name now looks like this “Name of computer\Paul”

  3. password not accepted for this user name either.

What’s going wrong here?
