When you try to access or work with files and folders in Windows, you experience one or more of the following issues:. To resolve a particular issue, follow the steps for the issue that best describes your situation.
Use the method for your version of Windows. If particular steps do not resolve the issue, try a different set of steps. You may not have ownership of a file or folder If you recently upgraded your computer to Windows 8 from an earlier version of Windows, some of your account information may have changed.
Therefore, you may no longer have ownership of some files or folders. You might be able to resolve this issue by restoring your ownership of the files and folders. To take ownership of a file or folder, follow these steps:. Press and hold the folder that you want to take ownership of, then tap Properties.
If you are using a mouse, right-click the folder, and then click Properties. Tap or click the Security tab, tap or click Advanced , then tap or click Change.
If you are prompted for an administrator password or for confirmation, type the password or provide confirmation. Type the name of the person that you want to give ownership to, and then click Check Names.
If you want this person to be the owner of the files and subfolders that are contained in this folder, select the Replace owner on subcontainers and objects check box. You may not have the appropriate permissions Issues that you experience when you try to access files and folders may be related to permissions.
Permissions are rules that determine whether you can access or change files and folders. To check permissions on a file or folder, follow these steps:. Press and hold or right-click the file or folder, and then click Properties. Under Group or user names , tap or click your name to see the permissions that you have. To open a file, you have to have the Read permission. To change the permissions of a file or folder, follow these steps.
Important You must be logged on as an administrator to change permissions on files and folders. Press and hold or right-click the file or folder, and then tap or click Properties. Tap or click Edit , tap or click your name, select the check boxes for the permissions that you must have, and then click OK. The file or folder may be encrypted Encryption can help protect files and folders from unwanted access.
You cannot open an encrypted file or folder without the certificate that was used to encrypt it. To determine whether a file or folder is encrypted, follow these steps:. Tap or click the General tab, and then tap or click Advanced. If the Encrypt contents to secure data check box is selected, you have to have the certificate that was used to encrypt the file or folder to be able to open it. In this situation, you should obtain the certificate from the person who created or encrypted the file or folder, or have that person decrypt the file or folder.
You may not have ownership of a file or folder If you recently upgraded your computer to Windows 7 from an earlier version of Windows, some of your account information may have changed. To take ownership of a file or a folder, follow these steps:. Right-click the folder that you want to take ownership of, then click Properties. Click the Security tab, click Advanced , then click the Owner tab. Note If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.
If you want this person to be the owner of files and subfolders in this folder, select the Replace owner on subcontainers and objects check box. To determine the permissions of the file or folder, follow these steps:. Under Group or user names , click your name to see the permissions that you have.
To change permissions on a file or folder, follow these steps. If you must use a domain account, create a brand new domain account and create a new domain security group you could call it something like "Guest Users" for that account to be in. Add the account to the group, set the new group as the user's primary group, and then remove the user from the Domain Users group. Now the user should have access to nothing on the domain, assuming again that you have not granted access to anything for the Everyone object, because no one could have granted access to anything in the past for a brand new user or group.
If you have granted access to anything for Everyone , or you have reason to think that Everyone might have any access rights to any resources, then you have to run that down and correct it. One object that you can almost always get away with using as a replacement for Everyone is Domain Users , because in general, every domain account is a member of Domain Users unless the account has been specifically removed, as described above.
Note that you should not change permissions to resources that your users are using during business hours, as they are likely to be denied access by your changes until the next time they log on and get a security token. Ideally, you would have some experienced consultants on-hand to help you with this kind of permissions change, since it's very possible to accidentally either deny users access to important resources or grant users access to confidential information.
If the computer s will never be used by full staff to need domain access, you can dedicate the computer s to guest access and not even join them to the domain. Finally, the ultimate separation for guests would be for the computer s in question to be on a separate network or VLAN from the domain computers, possibly sharing internet through a firewall with multiple physical or virtual interfaces, or even with a separate, dedicated firewall and internet connection.
Todd's points should also be considered before you decide how to implement this. The correct way to have guest access on a network that is separate from your production network is to have the guest network on a separate Virtual Local Area Network VLAN as Todd pointed out. A lot of people seem to think that allowing guest access to their network isn't a big deal and they can just flip a switch and have it work but not give those same guests access to their network.
That just isn't how this works. Planning saves a lot of headaches so if you think you might have a need to provide guests with Internet access but keep them out of your production network you should take the time to properly design and segregate your network using VLANs.
It isn't a small task but when configured correctly properly keeps the two networks segregated while giving both access to the Internet or other resources like printers or servers.

This policy setting supersedes the Access this computer from the network policy setting if a user account is subject to both policies. Any change to the user rights assignment for an account becomes effective the next time the owner of the account logs on.
Settings are applied in the following order through a Group Policy Object GPO , which will overwrite settings on the local computer at the next Group Policy update:. This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation. Users who can log on to the device over the network can enumerate lists of account names, group names, and shared resources.
Users with permission to access shared folders and files can connect over the network and possibly view or modify data. Why does "Access Denied" error appear?
