Hi Crahak, you're too kind to help me OK before I saw your answer I tried to fix with Dial-A-Fix.exe, witch is a very nice program but did not work. I also tried your code line in RUN for resetting the TCP/IP but no good. Same thing I can go on http://www.microsoft.com/windows/downloads/default.aspx then go on a file like IE 7 then when I click on download button it says '' can't open the page... bla bla bla, try refresh, bla bla bla, option, settings, automatic detect setting etc etc..... But always the same result: Cannot dls a dammed thing from Microsoft. Makes no blody sence, I installed Windows defender today it works but it cannot dl the updates, error code 0x80004002, then i search for that and I could go on microsoft to dl and install manualy but still the dls do'nt work !!!!!!!!!!!!!! Next step I guess I will reformat for the third time in a month................ Question :What did you mean by: ''You could also post a hijackthis log, and we'll have a look''. Thank's for all your help going to bed it's late Laurent
