Can not ping device in VLAN

I can not ping a computer that I've connected to VLAN10 on a 3560 switch I've just setup. I've setup a 3560 switch connecting to a 3550 switch as follows:

(Building A - 3560)
interface GigabitEthernet0/1
 description Uplink to Building B
 no switchport
 ip address

interface Vlan10
 description MANAGEMENT VLAN
 ip address

 ip route

(Building B - 3550)
interface GigabitEthernet0/4
 description Uplink to Building A
 no switchport
 ip address
 ip route-cache flow

 ip route

              I can ping the vlan interface from Building B - 3550, but I can not ping the computer I have connected on fa 0/1 on Building A - 3560. Here is how I have the interface configured.

interface FastEthernet0/1
 switchport access vlan 10
 spanning-tree portfast

I have the computer setup with a static ip address

I can ping the vlan interface from the computer. But I can not ping anything in Building B - 3550.
Can anyone point me toward a solution?

    I don't see any reason why this shouldn't be working; do you have a second PC you can put on another port on VLAN 10 and test connectivity between the systems?

    If you look at the ARP cache on the PC and the switch does it show the right MAC addresses?

    I have some meetings this morning, and will check as soon as I can.

    The arp cache on the  switch shows the correct MAC addresses.  I have also set up another computer on the same vlan 10 and gave it an address and it can not ping the computer.

    Computer A and B are  on same VLAN 10
    Computer A ( can ping everything.
    Computer B ( can ping everything except Computer A (
    Everything can not ping
    Everything can ping

    It looks like something is wrong with my Computer A, because everything seems to be working right on Computer B.  WEIRD!!!!!

    Is there a FW running on computer A?

    If not I'd try swapping ports and cables between A & B and if it follows Computer A it has to be someting on the PC.  At that point I'd load Wireshard and take a capture on Computer A to see exactly what the PC is seeing.
