Ok as i said before...i'm not really good with windows and you know what...i'm proud of that :p
So keep in mind that windows is a feckin O.S and the behavior of firefox under Linux is not the same in windows.....and thus i have set the url
http://your-sme-ip/server-resources/regedit/ firefox goes to
http://www.server-ressources/regedit.
I tested the same url with firefox and linux, and the results was different because I have exactly the url of regedit keys....be aware of that.
so after that you need to save the key win7samba.reg somewhere in your W7 tree folder and start "regedit" by the start menu of you W7.
Then you can open the menu file/import and look to "all files" and apply with your "win7samba.reg"
once you have applied this file you can try to log to the (Koozali) SME Server.
That's all folks.....what i don't understand it is why there are not a wiki page on this subject....i will do it :p
