Reverting IIS Auto Logon settings from CRM registry

Once while accessing the sage CRM, I enabled the IIS AutoLogin feature. After this CRM did not allow me to login into CRM again even though when I entered the right windows credentials and also my username exists in active directory of domain. So this might have been because i might not have configured active directory and domain credentials correctly while enabling autologon. Hence to modify them tried logging in to CRM, but was not able to do so through any way as Auto logon was already enabled.
I followed the below steps to revert autologon settings and set all the credentials in CRM after logging in to get Windows logon to work
 1. Go to Start  | Run.
2.  Type Regedit and hit Enter.
3.  Browse to the node “HKEY_LOCAL_MACHINE | SOFTWARE | eware | Config | CRMInstancename”.
4.  Here the Key UseIISAutologin will be set to ‘Y’.
5.  Set this key to ‘N’.
6.  Restart  IIS using IISRESET command.
