Hi,
This is my blog site for example: http://www.mydomainname.com/Blog
If I set the permalink to default i can browse to this link : http://www.mydomainname.com/blog or this http://www.mydomainname.com/BLOG
but if i change the permalink to month and year i can't browse anymore to this link: http://www.mydomainname.com/blog (I get page not found)
My hosting is godaddy with IIS7
Does IIS7 natively support rewrite rules or is it still a separate purchasable module?
"My hosting is godaddy with IIS7 "
That's your problem. :D
Did you ask support and see what they say?
Is i've asked them, they told me its wp problem. and again, if i disable the permalink, it works great.

Does IIS7 support re-write rules?
If it doesn't then that is your problem, pure and simple. WMPU needs rewrite rules to support fancy permalinks, amongst other things.
