I am plugging a Catalyst into a Procurve. The catalyst port 1 goes green then amber about 4 seconds later. I console into the switch. I have the port unplugged then I plug it back in. I get this....

00:02:23: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to down
00:02:24: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
00:02:24: %SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk FastEthernet0/1 VLAN1.
00:02:24: %SPANTREE-7-BLOCK_PORT_TYPE: Blocking FastEthernet0/1 on VLAN0001. Inconsistent port type.
I don't see any errors on the 4104.

Computers plugged into this switch don't get DHCP or if I use a static address get network activity to other devices other than on this switch.

I am thinking of using the "no spanning-tree vlan 1" on the catalyst.  

Should I be looking in another direction or should this fix the message and get this switch working.

What is the configuration of the port on the 4104 side?  I wouldn't recommend disabling spanning tree.  You could change the mode of the switchport on the 2950 side to trunking to see if the link comes up and builds a trunk with the 4104.  If it does, I would find out why the 4104 is attempting to trunk and change it to a standard access port if trunking is not needed.

conf t
int fa0/1
switchport mode trunk

Sorry but I used    
"no spanning-tree vlan 1"

The port came up and there is connectivity.

Just be aware of the risks involved when not running STP.

make sure u use proper encapsulation

conf t
int fa0/1
switchport trunk encapsulation dot1q

in HP swith u have to use tagged command
trunk command in HP swicthes is equal to etherchanel command in cisco switches
