How did you set up DNS?  Does the cluster have an A record or a CNAME
at the moment?

If DNS is in order, you most likely have an issue with kernel mode
authentication, which essentially means the machine's account, not the
custom domain account, is trying (and failing) to decrypt the ticket.
This is a new default behavior with IIS7.

Read the section "Kerberos authentication and Kernel Mode Authentication" here:
