Come for the solution, stay for everything else. Welcome to our community! I have one share on my network that I need to allow anonymous access to, without prompts, and all attempts thus far have been unsuccessful. The Server in question is a domain member, but not a DC. So far: --I enabled the Guest Account, and gave it a password.
Any Help? Thanks in Advance. Darius Ghassem. Most Points The Distinguished Expert awards are presented to the top veteran and rookie experts to earn the most points in the top 50 topics.

Privacy policy. This article describes information about Windows disabling guest access in SMB2 and SMB3 by default, and provides settings to enable insecure guest logons in Group Policy. However, this is generally not recommended. This default behavior was previously implemented in Windows 10 but later regressed in Windows 10 , Windows 10 20H2, and Windows 10 21H1 where guest auth was not disabled by default but could still be disabled by an administrator.
See below for details on ensuring that guest authentication is disabled. If you try to connect to devices that request credentials of a guest instead of appropriate authenticated principals, you may receive the following error message:.
You can't access this shared folder because your organization's security policies block unauthenticated guest access. These policies help protect your PC from unsafe or malicious devices on the network. Also, if a remote server tries to force you to use guest access, or if an administrator enables guest access, the following entries are logged in the SMB Client event log:. This event indicates that the server tried to log on the user as an unauthenticated guest but was denied by the client.
Guest logons do not support standard security features such as signing and encryption. So, guest logons are vulnerable to man-in-the-middle attacks that can expose sensitive data on the network. Windows disables insecure nonsecure guest logons by default. Normally, you would want to leave this check box selected. From a Windows administration standpoint, it is considered to be bad management to deselect this check box.
The reason is that if you disable inherited permissions, then it tends to become more difficult to figure out what permissions belong to which folder. This is another check box that can get you into trouble. I strongly recommend never using this one. Earlier I mentioned that the last column of the Permissions properties sheet tells whether the permission applies only to the current file or folder, or to subfolders as well. If you select this check box, then any permissions that show on the Permissions tab as being applicable to subfolders will be applied to subfolders.
The catch is that these permissions will override any permissions that have been explicitly assigned to subfolders. You will almost never want to do this. Effective Permissions I have talked a lot about the effective permissions for a file or folder, but I have not yet answered every question.
Earlier, I stated that it was possible for a user to belong to multiple security groups that have contradictory permissions to a resource. In Windows , you had to calculate the effective permissions for the user yourself by examining which permissions belonged to each group. However, Windows Server makes this process much easier. To find effective permissions, return to the Advanced Security Settings properties sheet for the file or folder that you are working with, and select the Effective Permissions tab.
This tab allows you to enter a user name or a group name and will then display the effective permissions for that user or group. This takes all of the guesswork out of securing a file or folder. Ownership The last aspect of file security that I want to discuss is ownership. Every file on an NTFS partition has an owner. The owner is the user who created the file or folder.
The owner is allowed to control who has what permissions to the file or folder. The reason that I want to discuss this is because sometimes it's necessary to change ownership. For example, suppose that a user creates a folder and assigns some inappropriate permissions to the folder. To take ownership, an Administrator would open the Advanced Security Settings properties sheet for the folder, select the ownership tab, and then use the Change Owner option.
There is also an option to change the ownership on all subfolders. Taking ownership of a file or folder is not purely an administrative function though. While it's true that an administrator always has the option of taking ownership of a file or folder, anyone can take ownership of a file or folder if she has been assigned the right, Take Ownership Of Files Or Other Objects. The Restore Files And Directories permission also allows someone to take ownership if necessary. When doing so, this only allows the recipient to take ownership of the current file or folder.
It does not give the recipient global permissions to take ownership of any file or folder. The recipient actually has to take ownership to complete the process. Easier than it seems As you can see, file permissions are relatively complex. However, Windows Server makes it much easier to accurately assign permissions than previous versions of Windows did. You have plenty of flexibility when assigning permissions.
Just be careful when assigning permissions so you don't create conflicts that can lead to troubleshooting headaches later. Editor's Picks.
