Windows 7 Pro file sharing permissions with user and password not accessible by other computers

try this:

where it asks for a username, put it in the following format:


computername\username

so if the computer you are sharing from is called PC1 and the user is aaaa

the username would be PC1\aaaa

Make sure taxdata is c:\taxdata and not  buried down in your users folder.

Go to Control Panel, Network and Sharing Center, Advanced Sharing Options.

Make sure you are using Home/Work and not Public.
Make sure Network Discovery is on All computers.
Make sure File and Print Sharing is on All computers.
Turn off public sharing All computers.
Set for 128-bit encryption All computers.
Turn on Password Protected sharing All computers.
Set for User Accounts and Passwords All computers and don't use Home Group for this.

Restart all the computers and try accessing again. I use the above method and it works on my Windows 7 computers.

when i removed the everyone it does not prompt for any user/password anymore.

to Thinkpads_User
the setup configuration for network as listed in your  answer has been my configuration.

no solution yet on sight.  

i can see from computer 2 the shared folder on computer 1. but, when i expand it, then pops up a window with the error: you don't have permission to access this folder. see your network admin....

Open a regular command prompt one of the machines trying to access. Type:

NET USE Z: \\nameofwin7PC\foldername   and press enter. Authenticate.

What answer do you get?   Is taxdata in the root of C?  I was not clear.

@Forinsight,  

Try the following:

On the machine with c:\taxdata, set up a user of the other machine. So right click on Computer, select Manage, Local Users and Groups, Users and add the userid and the password from one of the machines trying to access C:\taxdata.  

Then restart both machines and try again using NET USE so we can see the errors.

Thanks, .... Thinkpads_User

"add the userid and the password from one of the machines trying to access C:\taxdata. "
the problem with this is that there is only one 'Locations" i could add user and that is the local workgroup, whichis the computer having the share. there is no option i could see that i could add other computer's users of the same workgroup.

i'm sure you could help me  with this because you helped once with just one statement i solved my problem.

thank you so much for your  snapshot. yes indeed i was on that spot. when you said that i need to add the user of the computer connecting to the computer with the share, you meant that i need to add the user by accessing the user from the 'Location" of the computer trying to connect, ie: *Locations, *computer2(one connecting), then find the user. then i can add it from the network location.

so what you mean is that i just have to duplicate the username of computer2. i'll do that now.

i added the computer user and password. the same result. nothing
added it even to the administrators. no difference
added it to the shared folder's access permissions. no difference. all the while both computers were restarted before trying to test the share.

prompted for username and password.
'system error 5 has occurred. access denied.' did verify password. it's correct.

@Forinsight - Thank you. I was very pleased to help you with this.
