I have three computers running Windows 7 and I am having networking issues. All three computers have three different users. One is a guest account, one is an Admin account (it's user name is the same as the computer name) and then one account for me. All passwords are the same. The network that is set up is a Work Network. Password protected sharing is off. And the credentials in the credential manager are correct for all computers. However, sometimes I can move files from one computer to another via the "My Computer" and sometimes I get the message "You need permission to perform this action." And other times I am asked to supply a password... I am frustrated beyond belief at this point because I see no reason why these computers cannot share with each other. Is there anyone out there that can help? Any help is appreciated... Thank you in advance.

It could also be because of User Account Control (UAC) User Account Control (UAC) is a feature in Windows 7 that can help prevent unauthorized changes to your computer. UAC does this by asking you for permission or an administrator‌ password before performing actions that could potentially affect your computer's operation or that change settings that affect other users. To Change User Access Control (UAC) settings click on the following: Adjust User Account Control settings in Windows 7 Disabling User Account Control (UAC) in Windows 7 User Account Control Step-by-Step Guide A restart is required after disabling UAC. Additionally the User accounts need to have the administrator rights <If this post helps to resolve your issue, please click the "Propose as Answer" If you find it helpful , mark it as helpful by clicking on "Vote as Helpful" button at the top of this message.

The differences between a workgroup (work network) and a homegroup (home network), from Help and Support: In a workgroup: All computers are peers; no computer has control over another computer. Each computer has a set of user accounts. To log on to any computer in the workgroup, you must have an account on that computer. There are typically no more than twenty computers. A workgroup is not protected by a password. All computers must be on the same local network or subnet. In a homegroup: Computers on a home network must belong to a workgroup, but they can also belong to a homegroup. A homegroup makes it easy to share pictures, music, videos, documents, and printers with other people on a home network. A homegroup is protected with a password, but you only need to type the password once, when adding your computer to the homegroup. The location of where you are moving the files from is pertinent. If you have not set up Libraries ( Public folders), when you select files in your personal User Account folder (your User Account's named folder) you will be prompted for a password/username unless you first right click it and choose Share with. Then set the sharing to what you want, eg. Homegroup (Read)/ Homegroup (Read/Write), etc. Anything shared that is outside of the Library can be shared by using Advanced sharing - Right-click a drive or folder, click Share with, and then click Advanced sharing. In the dialog box that appears, click Advanced Sharing. If you're prompted for an administrator password or confirmation, type the password or provide confirmation. In the Advanced Sharing dialog box, select the Share this folder check box. To specify users or change permissions, click Permissions. Click Add or Remove to add or remove users or groups. Select each user or group, select the check boxes for the permissions you want to assign for that user or group, and then click OK. When you've finished, click OK. Note You can't share the root of a drive with a dollar sign following the drive letter as in versions of Windows earlier than Windows Vista. For example, you can't share the root of your C drive as "C$," but you can share it as "C" or any other name.

Thank you everyone for your assistance. This cleared up some of my problem, but unfortunately, I am still having one issue... One of my laptops continues to ask me for a user name and password when I log into the other laptop. I have utilized the advanced sharing and the credentials manager and I still cannot find the problem. Is there anywhere else I need to look?
