Can't serve ASP files in IIS

I installed Windows Vista beta 2 and also IIS7 on my computer to include the subcategories under it. I want to run a program that requires IIS and if I am running the program then it will give me the below 404.3 error:

HTTP Error 404.3 - Not Found
Description: The page you are requesting cannot be served because of the
Multipurpose Internet Mail Extensions (MIME) map policy that is configured on
the Web server. The page you requested has a file name extension that is not
recognized, and therefore is not allowed.

Error Code: 0x80070032

Notification: ExecuteRequestHandler

Module: StaticFileModule

Requested URL: http://localhost:80/Web-Link/default.asp

Physical Path: C:\inetpub\wwwroot\Web-Link\default.asp

Logon User: Anonymous

Logon Method: Anonymous

Handler: StaticFile

Causes:

The appropriate MIME map is not enabled for the web site or application
Solution:

Verify that the MIME map is enabled or add the MIME map for the site. From the Web Management tool, open a connection to the website. Double click the MIME Types Management feature. Verify that the MIME type is in the list and is not set to Removed. If the MIME type is in the list and set to Removed, highlight the MIME Type in the list, and in the MIME Types Tasks, click Restore. If the MIME Type is not in the list, complete the MIME Type information in the Tasks pane under New MIME Type, and then click Add.
NOTE: Make sure that this MIME mapping is needed for your Web server before adding it to the list. Set up a new Failed Request Trace rule for this HTTP status code. Use the IIS Web Management tool to open a connection to the Web server where the problem is occurring. In the tree view, navigate to the Web site, and then click to select it. In the Tasks pane, click Failed Request Tracing. Check Enable Logging for this Site, specify a logging folder or use the default log folder, and then click OK. Open the Failed Request Tracing Rules feature and click New Rule in the Tasks pane. Specify the content type to monitor and then click Next. Check the Status Codes checkbox, type 404.3 in the Edit box, and then click Next.

After doing some research I ran the command from the actual command prompt and it seems to have worked for me but still am getting the same 404.3 error. I also found out that the checkboxes under Control Panel and then Programs and then Windows Features and enabled them, but still cant serve the default.asp page.

Can you go to Control Panel and then go to Uninstall or Change program. After that, here you have to tuen on or off, Internet information services check box. Just note that the check box has a tick or only a colour, incase if it has colour only then means you did not enable all the features including .asp support. After that you need to click the + sign near to the check box and then get into it and find the .asp support page and enable it. Hope this helps.
