shared memory opening permissions windows

i've grown windows concentration uses common memory---that is---memory mapped files interprocess communication. i have windows use does guess intermittently writes information memory mapped file. i have removed windows concentration reads memory mapped record displays information. concentration works approaching windows xp, xp pro server 2003, nonetheless vista.

i information being combined memory mapped record duty justly windows use since i open record calm editor stored messages, nonetheless "consumer" concentration can't review file. engaging thing note here, i tie consumer concentration restart it, consumes messages formerly combined memory mapped file.

also, another uncanny thing i same function i bond windows horde controlling remote desktop invoke/use consumer concentration by remote desktop. however, i plead remote desktop bond aim host's console event following command: mstsc -v:servername /f -console, all works perfectly.

so that's since i cruise problem associated permissions. anyone critique this?

edit:

the acl i'm controlling emanate memory mapped record mutex objects sychronize opening follows:

tchar * szsd = text("d:")
               text("(a;;rpwpccdclcswrcwdwogafa;;;s-1-1-0)")
               text("(a;;ga;;;bg)")
               text("(a;;ga;;;an)")
               text("(a;;ga;;;au)")
               text("(a;;ga;;;ls)")
               text("(a;;ga;;;rd)")
               text("(a;;ga;;;wd)")
               text("(a;;ga;;;ba)"); 

i cruise competence biased issue.
