ASP.net Form Authentication allow access to "/" vb.net - asp.net

I'm struggling to get around this problem with form authorization. I've got it all working as it should, people can only access the pages i specify apart from the root. By that i mean if they go to www.mysite.com they get the unauthorized access page but if i go directly to default.aspx, it works fine.
I'm still learning for please forgive me if it's something blatantly obvious :)
Here's my webconfig code:
<forms name=".ASPXFORMSDEMO" loginUrl="Logon.aspx" protection="All" path="/" timeout="30" defaultUrl="Default.aspx" />
</authentication>
<authorization>
<deny users="?" />
<allow users="*" />
</authorization>
</system.web>
<location path="Default.aspx">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
I've set my default doc in IIS to default.aspx but that's not fixed it.
How to i allow all user access to the root of my site?
Thanks all!
Update: I've tried this:
<location path="/">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>
but i get a HTTP Error 500.19 :(
Updated: i've answered my own question - even though i cant answer it yet on here!
Well, it looks like i was doing it wrong - i've now changed to allow all pages and block the folder/pages i want like this:
<forms name=".ASPXFORMSDEMO" loginUrl="Logon.aspx" protection="All" path="/" timeout="30" defaultUrl="Default.aspx" />
</authentication>
<authorization>
<allow users="*" />
</authorization>
</system.web>
<location path="Admin">
<system.web>
<authorization>
<allow users="username"/>
<deny users="*"/>
</authorization>
</system.web>
</location>

How can i exclude my register page from Form Authentication Redirect to login page

as the title says, i am trying to exclude a few pages such as my register.aspx from Form Authentication Redirection, here is my web.config
<authentication mode="Forms">
<forms name="MyAppCookie" loginUrl="Login.aspx" protection="All" timeout="120" defaultUrl="Default.aspx"/>

Use the location tag in your web.config.
<location path="register.aspx">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>

<location path="Login.aspx">
<system.web>
<authorization>
<allow users="?" />
</authorization>
</system.web>
</location>
<location path="Content">
<system.web>

</location>
<location path="fonts">

</authorization>
</system.web>
</location>
<location path="Scripts">
<system.web>
<authorization>
<allow users="?" />
</authorization>
</system.web>
</location>
I searched and tried several solution but no chance have you any idea?
Simple Forms Authentication from MSDN
<system.web>
<authentication mode="Forms">
<forms loginUrl="Login.aspx" name=".ASPXFORMSAUTH">
</forms>
</authentication>
<authorization>
<deny users="?" />
</authorization>
</system.web>
very clear and good article I have in bookmarks http://weblogs.asp.net/gurusarkar/setting-authorization-rules-for-a-particular-page-or-folder-in-web-config
Finally i made a workarround like this
I deleted this part :
<authorization>
<deny users="?"/>
</authorization>
then I modified the locations tags like this :
<location path="Login.aspx">
<system.web>
<authorization>
<allow users="?"/>
</authorization>
</system.web>
</location>
<location path="Default.aspx">
<system.web>
<authorization>
<deny users="?"/>
</authorization>
</system.web>
</location>
<location path="Users.aspx">
<system.web>
<authorization>
<deny users="?"/>
</authorization>
</system.web>
</location>
<location path="Content">
<system.web>
<authorization>
<allow users="?"/>
</authorization>
</system.web>
</location>
<location path="fonts">
<system.web>
<authorization>
<allow users="?"/>
</authorization>
</system.web>
</location>
<location path="Scripts">
<system.web>
<authorization>
<allow users="?"/>
</authorization>
</system.web>
</location>
So when I tru to go to default or users page i'm gettting redirected automatically to login page.
I really searched a lot to understand what i'm doing wrong but didn't find out so I'm adopting this solution for the moment.

Problems Creating correct location element in web.config for asp.net site

I have a test site on the web that I want to block all annoymous access to except logged in users. I also want to have annoymous access to just my login page (account/login)
I don't know how to exclude one path but even the below does not work, forgetting about the path.
<location path="">
<system.web>
<authorization>
<deny users="*" />
<allow users="?" />
</authorization>
</system.web>
</location>
Ideally, the following web.config setting should work. Make sure you update two Login.aspx with your login page.
It basically does not allow anonymous access except Login page.
<configuration>
<system.web>
...
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx" />
</authentication>
<authorization>
<deny users="?"/>
<allow users="*" />
</authorization>
</system.web>
<location path="~/Login.aspx">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>
</configuration>
