In a workgroup environment when you give share and network permissions to everyone, does everyone means ( every user on that particular pc ) or everyone means ( every user in the workgroup even if it does not exist on the local pc ) In both cases if when asked for credentials I enter the local admin with password of the pc which hosts the shared folder I should never encounter any authentication issue, is this correct ?

Everyone means everyone, literally. Anyone that connects to your network will have access to that share, regardless of whether their PC's a member of your workgroup or not. And with "Everyone" access you shouldn't be asked for authentication. If you are, your NTFS and Share permissions don't match.

Yes it means every person even he is not member of your local groups. In the case where everyone has share and NTFS permissions, you local users in both machines should have no empty passwords to avoid problems when accessing your shares. (If there is accounts with empty passwords you can be asked for authentication even if you give NTFS and share permission for everyone) Please remember to click “Mark as Answer” on the post that helps you, and to click “Unmark as Answer” if a marked post does not actually answer your question.

If on the Share and NTFS permissions I set both of them to everyone with full permissions and make sure that the local user have a password setup, I should not have any trouble at all to access the file from another pc on the network and it should not even ask for authentication if I specify the full UNC path directly either from the RUN of another pc or from the SCAN TO FILE from the printer which I will use for scanned docs correct ?

Yes, I always do like that and I have no problems. The last time I checked it was the last day. (If you've got a problem with the configuration of your internal firewall, shares may be not accessible) Please remember to click “Mark as Answer” on the post that helps you, and to click “Unmark as Answer” if a marked post does not actually answer your question.

Hi All, Only one correction: In Windows 7 “Everyone” only includes every user except Guest account of the local system. The system cannot recognize any credentials of other systems. To access shared recourses of the local computer, wherever you access it from, you need to use a valid credential of the local computer. When you try to setup the shared printer/scanner, it should ask for credentials. Then Windows will remember the credentials so that username and password are not required the next time when you access.
