This got to be something simple but I can get it working 
What do I need to do to get the protocol "up"?
router00#show ip interface brief
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned YES manual administratively down down
FastEthernet1/0 192.168.1.1 YES manual up down
Serial2/0 192.168.2.1 YES manual up up

What's it plugged into? A switch with VLAN set and active? Correct Cable? FA1/0, right?:mike: Cisco Certifications -- Collect the Entire Set! -

speed/duplex settings on both ends - are they set to auto? if so, try to set them explicitly“You don’t become great by trying to be great. You become great by wanting to do something, and then doing it so hard that you become great in the process.” (c) xkcd #896

Is there any assigned ports to that vlan?
Have you created the vlan the port is in? -

Probably a Packet Tracer bug.
I tried an 1841 router (FA0/0) attached to a 2960 (FA0/1) and it didn't work. FA0/1 on the 1841 would work. The 2960 did auto configure at half duplex, but hard coding it didn't fix the problem. And when I replaced the 2960 with a 2950, then FA0/0 on the 1841 worked.
With packet tracer, what doesn't work (that should) with one type of device may work with another device -- so try a different router or switch with the same configuration.
And the fall back option of any simulator -- save your work. Exit the software. Then reopen the software and reload your topology and/or configurations and see if it now magically works.:mike: Cisco Certifications -- Collect the Entire Set!
