   <configurationredirection enabled="true" password="[enc:IISCngProvider:X0ObCWwZ4+PrTHiFVPtzFeCcL8u5P6KUOYfo1/0QrgZWATA5pKWqHvD8nL2crNJKyyqr4z/rBdLPjdRcaLxAMMj4l+lvp5EXXKSXueolvyGa34F4QZfbBVCM6oVNcq3M368TOTVjJv4POVFQWvu0MDVlGgReglXB+Lw5BRI4Htw=:enc]" path="C:\Windows\System32\inetsrv\config\import\" username="Administrator"> </configurationredirection"></li">
   
   you need to change this to
   
   <configurationRedirection />

5. please check the "Enable Shared Configuration" and select the path specified in the your configurationredirection (please check with yelow backgound)
   
   <configurationredirection enabled="true" password="[enc:IISCngProvider:X0ObCWwZ4+PrTHiFVPtzFeCcL8u5P6KUOYfo1/0QrgZWATA5pKWqHvD8nL2crNJKyyqr4z/rBdLPjdRcaLxAMMj4l+lvp5EXXKSXueolvyGa34F4QZfbBVCM6oVNcq3M368TOTVjJv4POVFQWvu0MDVlGgReglXB+Lw5BRI4Htw=:enc]" path="C:\Windows\System32\inetsrv\config\import\" username="Administrator"> </configurationredirection"></li"> 
6. Then go to the machine.config file and revert the configurationredirection to previous setup that is
   
   <configurationredirection enabled="true" password="[enc:IISCngProvider:X0ObCWwZ4+PrTHiFVPtzFeCcL8u5P6KUOYfo1/0QrgZWATA5pKWqHvD8nL2crNJKyyqr4z/rBdLPjdRcaLxAMMj4l+lvp5EXXKSXueolvyGa34F4QZfbBVCM6oVNcq3M368TOTVjJv4POVFQWvu0MDVlGgReglXB+Lw5BRI4Htw=:enc]" path="C:\Windows\System32\inetsrv\config\import\" username="Administrator"> </configurationredirection"></li"> 
7. Then go to Shared configuration and export the configuration 
8. after this again change the machine.config configurationredirection  tag to
   
   <configurationRedirection />
9. Now again import the Configuration from the Shared configuration from the Shared configuration in IIS.

This will also fix the IIS settings.
