Reporting Services is not working after Changing Machine Name

When I changed machine name and restarted machine SQL Server is working fine
But Reporting Services (Standard edition, SP2) was not working anymore. I ran
rsconfig utility passing new name . But After that I am just receiving
database and reporting service version are not correct error message.
Is there any document or step by step process for Reporting Services before
and after changing machine name . So that it will work without reinstalling .
Thanks.

You need to back up and restore your encryption key when you change your
computer name. You can consult the Reporting Services Books Online on how
to do this. If you have already changed the machine name, you can either
change it back, backup the key, or delete the encrypted content in your
current state.
