IIS 6 Metabase Error on Restoration or Migration Rumi, April 30, 2011 If you are trying to restore IIS and receive an Invalid Signature error trying to restore the IIS Metabase you must make a small tweak to ensure you can restore the IIS Metabase to another windows server. What probably happened is that you created a backup to the c:\windows\system\inetsrv folder and copied it to the new server and tried to restore IIS but you get Invalid Signature. The problem is that you didn't set a password so the backup is not portable. So simply redo your work. Create a new backup of the IIS Metabase and choose the option to "Encrypt Backup Using Password" and assign it a password. Then recopy the backup configurtion to the new server in the c:\windows\system32\inersrv folder. Then retry to restore IIS and point to your copied backup files. This time it will ask for a password and will restore IIS successfully. Administrations Configurations (Windows)
