Get Permissions yields always 511 or 365 and owner and group null

Question

Dear users,
I am trying to solve a write permission problem on a NTFS (Windows2003) server and on my local computer. There are various folders on the server, for which I do or do not have write permissions. Using "Get Permissions" I am trying to decide, whether I am allowed to write there  some data or not -- to avoid any error message. Running Get Permissions on both kinds of folders yields "511", which means. I do have a write permission (right?). There is no difference, between the two results, but in practice writing into one of these folders results in error.
Experiment: I created a folder locally, for which I removed all of my permissions. Currently I cannot open, write, or delete this folder. But Get Permissions still says that the folder has 511 permissions, i.e., write permissions for the executing user. Why? What could go wrong? What am I seeing wrong?
Kind regards,
p.s. the owner and the group are NULL ("", empty string) says Get Permissions, too. That is not also not awaited.

Hi, 
it seems like the VI is not as powerful as you want it to. The help to "Setting Permissions" states:
...This structure is based on the Linux permission bits that govern read, write, and execute permissions for users, groups, and others.
(Windows) Use of the permissions parameter is very limited on non-Linux operating systems. You can use permissions to change only write permissions for users (bit 7); the operating system ignores all other changes to the bits....
I hope this information helps.
Kind regards
