How to set permissions on a folder residing on vista system through C#

Manually set permissions are getting lost frequently. I gave 'EveryOne' fullcontrol permissions to a folder, after 10min to 1hr, the permissions are getting lost. Also I am not able to handle this issue from C#. Please help. Is there any hotfixes for these type of issues. Thanks in advance.

1) Permissions take affect when someone logs on. If you change them while
they are logged on they will not take affect until they log off and logon
again.

2) Don't use C#, use C$.
