Tracert Strange Behavior

Vista Ultimate tracert command returns only the destination address and
transit time. Route to the destination is not traced. Not on a vpn and
when I reboot into XP (dual boot config) tracert behaves normally. Also
tracert command in Vista in a VMWare Virtual Machine on the same PC
(Vista host OS, Vista guest OS) behaves normally. So must be a config
setting with the host Vista OS but can't figure out what. Any help or
ideas appreciated.
Tracert command looks like this:

C:\Windows\system32>tracert cc.usu.edu

Tracing route to cc.usu.edu [129.123.1.117]
over a maximum of 30 hops:

1 72 ms 73 ms 71 ms gumby.usu.edu [129.123.1.117]

Trace complete.

Any help or ideas appreciated.
