Are you running Sendmail as well?  If so, did you change your nameserver
configuration lately?  Sendmail can wedge a startup pretty hard.

I doubt that.  NFS is the last service to be loaded.  By the time NFS even
starts, telnet and ftp are all already running under inetd.  Something
else is amiss.  NFS will merely log an error if a shared directory is
missing.

Toss a console (keyboard and monitor, if there's a graphics card, serial
terminal if not) on the machine and reboot (yeah, go ahead and frob to
power button).  Then, see what comes up on the console.
