network trace assistance

hello all,

trying to troubleshoot a network issue between our web server and oracle server and Im pretty sure we've narrowed it down to firewall or some kind of anti virus blocking on the windows (web) server but wondering what the below is trying to say. I have ran the whole trc file through the trcasst tool but comes back with nothing useful because nothing is being sent to the server

---i assume ntt2err is a network error but is ntresnt network reset?

ntt2err: soc 26 error - operation=5, ntresnt[0]=517, ntresnt[1]=104, ntresnt[2]=0

oracle resides on a Redhat

---output of trcasst
