Can't modify user permissions on a folder

I am trying to give another user write access to a network folder on Windows. When I try to make any changes to the folder permissions, I get an error message:

An error occurred while applying security information to:

\\computer\path\to\folder

Access is denied.


Everything I have found suggests taking ownership of the folder, but I am already the owner and the "Effective Permissions" dialog box says I have full control.

What else could be preventing me from making any changes to the permissions settings?

Ok, so you have ownership and permissions on the NTFS level. Do you also have write rights the to share it is on? –  Hennes Feb 13 '13 at 17:14
@Hennes: Yes. The effective permissions for the network share says I have full control. I am not the owner of the share, though. Just the folder. –  mcrumley Feb 13 '13 at 17:46
Just making sure. I've been bitten before by the cumulative effects of share permissions and NTFS filesystem permissions. And judging from my coworkers I was not the only one. –  Hennes Feb 13 '13 at 17:52
