To grant users write access to a file on a network share, what should you do?

To grant users write access to a file on a network share, it is necessary to utilize a security group. A security group is specifically designed for managing permissions and access control, allowing you to assign the appropriate level of access to its members. When users are added to a security group, they inherit the permissions that are set for that group, including the ability to write to shared files.

This approach is more efficient than adding individual users one by one, as changes made to the security group's permissions will automatically apply to all members, simplifying management. By using a security group, you can maintain better control over access rights and enforce security policies effectively.

Meanwhile, other methods mentioned, such as adding users to a distribution group, are intended for email distribution lists and do not provide any permission or access management capabilities. Adding them to the Everyone group grants access to all users, which is often not desirable due to security concerns. Similarly, adding users to the Authenticated Users group allows any authenticated user to access resources, but it does not tailor the access level specifically for write permissions in the same way that a security group would. Thus, utilizing a security group is the most effective and secure method for managing write access.
