Is the system normally connected to a network, and at the moment is not
connected, or is not getting a DHCP lease?

I would do as Jan says and watch as the system is booting.
Which service seems slow to start? I would bet it is a network-related
service -  sendmail, NFS or NIS binding, and the system is either unable
to resolve a hostname, or is unable to connect to the relevant server.

Just for fun, remove the swap from the fstab (I know this is a bad idea)
and any NFS mounted drives, then reboot.

Also boot it single user -  does it boot in an acceptable time in this
case? Again points to a network related problem.
