Permission issue on network share drive

I am using Windows 7 on work domain network.
One of the shared drives is mapped automatically when I logon with my domain user.
However, when I try to create a file or directory from my workstation in one of the mapped network sub-folders, I get destination access denied.
I have checked and I have all permissions on that folder.

The strange thing is when I log on on another workstation with the same user, I am able to create or delete files in that location.

I have tried disabling Windows firewall, disconnecting and reconnecting to the drive but still face the same issue.

There are two levels of permissions, Share permissions and NTFS permissions. If you have NTFS permissions to read and write and share permissions only to read, you’ll only be able to read the files.

Conversely, if you have read/write access to the share, but only read access NTFS, you won’t be able to write.

In this case, it sounds like the share only gives you read only access.

Edit:

I misread the question, I thought you were able to edit the file from the system hosting the share.

So another question then, is the share automatically mapped on the other computer it works from, or do you need to connect manually? The share on the workstation that automatically maps that you can’t edit may be connecting with a different username.
