Unable to map share from wd my book live 3tb NAS via Win7

I was playing around with the users accounts and I deleted the guest a/c.

Now when I try and access my map drive to a share private share it is saying unable to access it.

my pc is  in a workgroup called WORK and the WD NAS is in a workgroup called WORK too.

The share called doco is a private share.

I have a user a/c on the NAs called admin

now when I try ad map \192.168.1.10\doco to  drive it is saying log in. 

WORK\admin  and i put in the password for the admin a/c from the NAS.

It does not like the p/w

I have anotehr a/c called q

same thing it wont let me map the drive to it.

the public folder which has security of public has no problems.with me mapping a drive to it.

I also created a the same user accounts that are on the NAs on my win7 Pc but still no good.

Any idea what I am doing wrong ?

I have made it a public folder and i can access it.  but i want to do this with private access
