If you are allocated disk space on a LAN to store your files, you may not want everybody else on the LAN to have access to them. LAN users typically have a block of disk space reserved for files that others on the LAN can't see or access. Even if another user knows the name of the folder containing your files, he will get an error that he doesn't have permission if he tries to access them.
A Local Area Network, or LAN, provides shared access to resources for a group of computers that are physically close to one another. With a LAN, you can share Internet access, printers, disk space and even files among users connected to the LAN. However, not all resources are available to everyone and you will receive an error that you don't have permission if you try to access a resource that's not been made available to you.
User-Restricted Access to Files
Group Access to Files
If you have a need to share files with a subgroup of users on the LAN, for example members of your department, a network administrator can create a group for managing security. File access can be granted to any member of the group. If a user who is not in the group attempts to access files that are restricted to the group, he will receive an error that he doesn't have permission to access the files.
Access to Other Resources
In addition to file permissions, a LAN administrator can set up permissions for other shared resources. For example, a printer in the Human Resources department that has limited physical access because of the personal and confidential data contained in reports, can be restricted to individual users or to a LAN group. An attempt to print to a printer you do not have access to will result in an error that you don't have permission to do so.
Resolving Permission Errors
If you have a need to access files or other resources on a LAN but you receive the error that you don't have permission, talk to your LAN administrator. The administrator can retrieve the permissions on the resources you want to access and compare those with the permissions in your user profile. This will determine the additional permissions you need to have added to your profile and usually helps determine whom you have to speak with to secure those permissions.
