Will winpcap & tracetcp cause any problem to Netbackup & Win 2008

I'm contemplating to install tracetcp on our Netbackup NBU 7.1
media server but tracetcp requires winpcap.

As it's a production media server (& I can't have a laptop or
test server on this LAN switch anymore), any concern that
winpcap or tracetcp will cause a problem to the NIC/OS/
backup jobs?

We have been facing intermittent ftp job failures between
2 separate sites that goes through WAN & there's at least
9 hops between the ftp client & server.

'ping -r .....' uses icmp which may not show the hop where
the problem lies & I thought of using tracetcp to simulate
tcp21 (ie as closely as possible to ftp)

Wouldn't  it be better to do:
  tracetcp  destination_IP:ftp
to simulate a true ftp packet ?

I also find 'tracert destination_IP" is rather slow,
instead "tracert -d ..." is much faster

When the ftp got disconnected, the 'tracert -d ..." & ping (a script
that pings every single hop on the MetroWAN), did not show any
problem/timeout at all.

Now I found I can't do 'tracetcp ...' on the network as SYN packets
are blocked on the MetroWAN

Is there any freeware ftp client which could do a 'low-bandwidth'
ftp to simulate & capture a full trace so that we could narrow
down if this is a Telco, the remote end ftp or the switches/router/
firewalls in between that's causing the occasional disconnects?
