Change machine name after installing Sharepoint

I have tried only on a standalone machine. Follow the steps to sort out the issue

1. Change alternate access mappings in Central Administration
   
   1. Central Administration > Operations > Alternate access Mappings
      
   2. Edit each mapping so that it reflects your new server name
      
      1. Ensure port numbers are the same
         
2. Use stsadm renameserver operation
   
   1. 
      

      stsadm -o renameserver -newservername  -oldservername  

3. Rename Server
   
   1. My Computer > Properties > Computer Name (tab) > Change (button)
   2. Type in new name of server
   3. Reboot server
