If I want to reinstall IIS6 , I can back up the IIS configurations before,and restore them after reinstalling.There is no problem because IIS6 can be installed or uninstalled as an entirety.
In IIS7, we must chose the modules which we need and install them.If some modules are installed before and not installed after,when I try to restore the backup file ,it contains some certain configurations of the uninstalled modules,what will happen?
How can we avoid this situation?
