Windows – changing permissions for a network share takes longer on win2008 than on win2003, why is that

network-sharepermissionswindowswindows-server-2003windows-server-2008

Given a network share accessible for "everyone" in the domain, containing several 1000 files and folders

When I change permissions for this share from read/write to only read (or vice versa) on windows 2003, the change takes effect instantly.

When I do the same on a share on Windows 2008, the dialog stays open for a long time before closing when I click on OK, and the server appears to be accessing a lot of files.

What is the reason for this delay? Does Windows 2008 also change ntfs permissions for all files inside the share? If so, why doesn't win2003 have to do that?

I do not mind the delay, after all I do not have to change this stuff very often, but I am curious.
What are the differences between 2003 and 2008 in this regard?

It appears that you're using the Simple Sharing wizard on Server 2008+ which also transparently changes NTFS permissions. This is why you should always used "Advanced" mode sharing, as it does not try and "help" you.
