New Computer and New IIS problems with Windows Vista

[complete]

I am on a brand new VISTA computer now. I am doing ASP.NET development.
So I need to turn on IIS. When I do, I notice that the IIS feature is
not checked.

When I check it, it says that there is an error during the set-up
process.

But it seems to continue.

Then, at the end of its process, it give me another error

But it seemed that it worked because behind the error message, the items
appeared to be checked.

But it did not work. When I go back and look at the settings, I see that IIS
is not installed.

Any suggestions?
