I'd suggest doing some TCP traces, and submitting them to your provider.
A TCP trace is more effective for diagnostics - remember, traffic can be
policy routed by traffic type, so an ICMP trace may not reveal the info
required (ICMP packet is typically only 56 bytes in size). QoS features
on the routers will give you misleading results when relying on ICMP
alone.

I don't know of a Windows port - there is a linux version of
tcptraceroute available at http://michael.toren.net
I guess you could try compiling it under Cygwin to use with Windows....
Or try searching Google - someone may have already ported it.
