sun system not starting up

I was having some problems with my sun system so i did an Init 6. now it has been booting up for about 20 minutes and only gets as fare as stting default interface for multicast: add net {gateway machinename}. any sugjestions on what i should do to fix this.

While I am no expert it sounds like it's hanging up at the init script /etc/rc2.d/S72inetsvc. You can try pressing stop-a to get the ok prompt, then typing boot -s to enter single user mode. From there cd to /etc/rc2.d Hand execute
./S69init start
From there do the same for each file starting with an "S" higher than S69
./S71rpc start
This will narrow down where the problem is. I'm sure someone will have a better reply soon.
