Connection Manager Customization
On this page of the Internet Explorer 7 Customization Wizard, if you have already created a custom profile using Connection Manager Administration Kit (CMAK), you can import it into your installation package.
If you use a CMAK profile, make sure that the profile is specific to the operating system for which you are creating the package. CMAK creates a self-extracting executable (*.exe) file that installs itself on your user's computer. When your user clicks the custom icon to connect to the Internet, the custom dialer dialog box that you created as part of the CMAK profile appears.
Use specified custom profile
Select this check box if you have already created a custom CMAK profile, and then type the name and location of the profile. CMAK files include .cmp and .cms files. Service provider customizations are contained in the .cms file.
