| You cannot be seriously asking this question being a MCP. I am not one and I know the answer to that.
NTFS Gives MS windows more control over security. You can share a file to anyone but, NTFS allows you to specify groups and type of access.
I know atleast in one of the books you read had this in it if you go back and look.
Sorry, don't mean to sound sarcastic but, somebody had to say it.
Have fun studying | |

| The concepts of share and NTFS permissions are tricky at first and some students may require some additional tutoring. Webman, I am concerned about your comments in the previous posting. Stevet merely asked for clarification and your response, in my opinion, is out of line and too judgemental.
I want to show you how easy it is to criticize someone. Your statement "You can share a file to anyone but, NTFS allows you to specify groups and type of access" is incorrect in more ways than one. The most prevelant error is that you cannot share a file...you can only share a folder!
So, you see that it is easy to criticize. Be more supportive and humble in this industry and you will go further. | |

| Share and NTFS permisions are administered in much the same way. The main difference is that SHARE permisions have no local significance. They only apply to users who attach to your pc over the network. So if you have a share on your machine and I log into it locally those share permisions do not apply. Think of it this way: A share is an entity in its own sense that can be given permisions such as a Folder, Printer, CDFS, etc... If you have a folder named "xyz" and you share it from windows explorer and keep the default name which will be "xyz" you now have two seperate things; a SHARE, and a directory on your local machine. Two different things that can be given permisions seperately. Hence NTFS permisions which apply to the directory(folder) and share permisions which apply to the SHARE. I don't know if this helps but, at least I tried. | |

| Forgive me for sticking my foot in my mouth.
I am sure he is a grown man and can accept a little criticism.
WERE HERE FOR YOU STEVET, KEEP TRYING!

| His post does have the word difference in it, does it not? Is it not safe to say that share permisions and ntfs permisions are two different things? | |

| Difference in using permissions in sharing a file and NTFS security permissions?
Shared folders and files - Shared folder permissions control users access to shared folders. These permissions only apply when users connect to the folder over the network, they do not apply when the user accesses the folder on the local computer. Shared folder permissions apply to the shared folder, its files and subfolders.
NTFS Permissions - These are permissions assigned to individual files and folders on NTFS volumes that are used to contol access to these files and folders. NTFS permissions apply to local users as well as to users who connect to a shared folder over the network.
If NTFS permissions are more restrictive than share permissions, the NTFS permissions are applied.
Hope this helps. Even though i'm a MCPx2 i'm sure theres things you know that i don't.
Webman, try and be more helpful next time.
That is what these forums are all about.

| I think that there was a great many of us who worked hard to understand the difference between share and NTFS permissions. However, when you think about it logically, there is not much to it.
NTFS is a file system. Unlike FAT which contains no security on files, NTFS allows you to associate a Access Control List with each file that resides on a NTFS partition. Fat does not have this ability, and because many of us have so much experience with FAT(32) file systems it can be difficult to understand.
In order for a user to access a file that resides on a NTFS partition, that particular file must contain and entry within the ACL. Without that entry, the user cannot access the file. PERIOD. It doesn't matter if the file resides on the local machine, or if you access the file over the network. If the file resides on a FAT partition, you cannot assign access permissions, so anyone can access the file locally. The file must be in a shared folder for anyone to access the folder over the network.
When you share a folder, you can then assign permissions for access to users who connect throught the NETWORK.
If the file/folder is on the local machine (the machine the user signed onto), shared folder permissions do not apply. Only NTFS permissions apply, if the file/folder resides on a NTFS partition. If the folder/file is on a FAT(32) partition, there is no way to restrict access to a locally signed on user.
To simplify: Share permissions are only necessary when you are accessing a file from across the network. This applies if the folder is on either a FAT or NTFS partition. If the folder/file is on a NTFS partition, you must also grant NTFS permissions because of the file system. If the folder/file is on a FAT partition you cannot assign any permissions. | |

| Esexon said:"If NTFS permissions are more restrictive than share permissions, the NTFS permissions are applied. "
That is not quite correct. If share permissions and ntfs permission overlap, the most restrictive will prevail. It doesn't matter whether it is a NTFS or share permission.
Just a minor detail  |
