Vista - Adding Vista Features

I cannot add remove features of windows vista as i want to install IIS
on my computer but after 5 days struggle doing all possible solution on
internet(Every body giving different flavours of solutions on net). I
was unable to add features. I tried to add remove other features but
same problem that progress windows appears but after some time there is
message that not all program successfully installed. However an article
come into my consideration written last year by 'Adding Windows
Features Fails on Vista' (http://tinyurl.com/b8pd5e) which told that
its not IIS problem but add/remove features problem as microsft fails
to solve this bug and he gave cause of multiple languages but I did not
install/update any additional language except english but i am facing
the problem.

I have tried to contact microsoft via email and chat but first of all
they ask to submit bunch of dollars to get chat with their
representative.

As I am not crazy to install IIS or asp.net of microsoft, just studying
and want to complete assignment. Previously i worked with php, jsp thats
work fine without wasting time.

Can anybody help me ?

I have running vista ultimate addition on dual core with 2 gb of ram.
all updates are installed except languages.

or anybody can help as i succesfull to install IIS on xp but when I run
http://localhost their is prompt for user name and password. I did not
use any login or password during login windows. i have tried by entring
my login name which i use in login but facing same problem.
