Apache 2.2 - Vista premium, document root permission error

[twoduds]

Hello
I have installed apache 2.2 on Vista premium.
Vista's UAC turned off before apache insallation.
Apache installed as a administrator from command prompt.
Got success page "It works".
DocumentRoot under VirtualHost is the problem(page give me forbidden error saying server do not have permission)

<VirtualHost *:80>
ServerName phpwww
DocumentRoot "d:/

http://www/phpwww/htdocs"

<Directory "d:/

http://www/phpwww/htdocs">

AllowOverride None
Options All
</Directory>
</VirtualHost>

If i comment out DocumentRoot line, all works fine.

Am guessing some permission need to "d:/

http://www/phpwww/htdocs"

folder but don't know which one.

I tried giving IUSER, CREATOR OWNER, my self, Administrator full control but no luck.

Please help me out here...

thanks
