SYMPTOMS
Internet Explorer is configured to use Active Server Pages for automatic configuration, but the changes specified in the .ins file do not take effect.



CAUSE
When you use IIS as part of an ASP AutoConfig solution, the MIME (Multipart Internet Mail Extensions) type for .ins files must be set correctly.



RESOLUTION
The appropriate MIME type setting must be added to the Web site properties of the site hosting the AutoConfig.ins file.

For IIS 4.0, do the following:
 * 1) Click Start and Point to Programs.
 * 2) Point to Windows NT 4.0 Option Pack.
 * 3) Point to Microsoft Internet Information Server.
 * 4) Click Internet Service Manager.
 * 5) When the Microsoft Management Console opens, right-click the site that is hosting the AutoConfig.ins file. Click Properties.

Note: If you are in a UNIX environment, the file name will be "autoconfig.ins" (without the quotation marks).


 * 1) Click the HTTP Headers tab.
 * 2) Click the File Types button under the MIME Map section of the property page.
 * 3) Click the New Type button.
 * 4) In the Associated Extension field, type ".ins" (without the quotation marks.)
 * 5) In the Content Type (MIME) field, type "application/x-internet-signup" (also without quotes.)
 * 6) Click OK.
 * 7) Click Apply, and then click OK to close the Web site property page.
 * 8) Restart the Web service.

After the MIME mapping is added, the server will send the MIME header "application/x-internet-signup" with any file with a .ins extension. This informs the client browser of the type of file being downloaded.



MORE INFORMATION
An example of the Active Server Pages AutoConfig solution may be found in the IEAK Resource Kit. By default, these files are located in C:\Program Files\IEAK\Reskit\Corp\Asphelp.htm.
