Have you tried rebooting the system into single user mode?  To do this:

1) press STOP-A on the keyboard (assuming a Sun keyboard).  If you're doing
   this on the serial connection you need to send a CTL-Break sequence to the
   system and that will depend on your terminal emulation program.
2) type sync at the "ok>" prompt
3) type boot -s (the -s will get you into single user mode)

After the system boots it will come to a point where it will ask you for the
root password to enter system maintenance mode.  Give the root password. You
should be in at that point.  To me it sounds like you've made a configuration
change at some point and either it's:

a) looking for an NIS/NIS+ server or
b) it's looking for an NFS server and it can't mount some remote filesystem.

That's about all I can tell you at this point without more info.
