AFAIK, you don't need NIS or NIS+ setup to use Jumpstart. It just has
to be configured correctly to access rarpd, bootparamd, and tftpd.
Where is it failing and saying "no domain name"? After the tftpd
bootstrap or after the NFS-mounted install kernel has mounted?

If worst comes to worst, try taking the drive out and connecting it to
another SPARC system. Mount it and fix the file.

Or buy a CDROM.
