DirectorySecurity.RemoveAccessRule has different effects on Windows Server 2003 and Windows XP

Even the folder's or file's access rule protection is set to true by calling DirectorySecurity.SetAccessRuleProtection(true, false),

DirectorySecurity.RemoveAccessRule method can still remove folder or file access permission on Windows Server 2003. While in Windows XP, only if access rule protection is closed, folder or file access permission rule can be removed.


If the folder or file access rule protection is set to true, by default the action to remove the access permission rule will fail.

However, here are the testing results:

Windows XP: When access rule protection is set to true, removing access permission fails.

Windows Server 2003: When access rule protection is set to true, removing access permission still works.

Windows Vista: When access rule protection is set to true, removing access permission fails.

When access rule protection is set to false, removing access permission can work in all above operation systems.

Therefore, there might be some potential issue around foler or file access permission in Windows Server 2003.
