Changed domain admin password, now failed to create connection to domain controller

I think it is a simple question.

We changed the domain admin password, now we can restore a image using Ghost 11.5 software, but a warning is given:

Details for : create machine account
Failed to create an administrative connection to <domain> <domaincontroller>: acces is denied
 

Shoud we change the <Tools> <Supported domains list> and then de administrator password?
Or change the password of the ghost service account on our AD?
Or both?
When we change this, which other consequences could happen?

Everything works great when pulling an image, not pushing the image to the pc's.

Can anyone  help me?

Thanks in advance.
