L3 switch device not pinging

All, I have a 3750 stacked switch with 2 or so svi interfaces. Vlan50 and Vlan204.

A device which is hardcoded as switchport access mode is on the 50 vlan. I can ping the device, which has an IP of from its source vlan 50 ip of  When I try and ping 56.15 from another vlan svi say vlan204 I get no replies.

I can ping every other device on the 50 vlan from vlan 204 but that one device. The device in question is an NTP server from Spectracom.

Its odd that I can source it from the vlan50 int and receive a reply. This means to me that the NTP server does know how to route to its default GW of

But why wouldnt it be able to be pinged from the 204 vlan?

Any help would be much appreciative.

I can telnet into the NTP server, however I dont have credentials, as the customer doesnt own that box.
