pathping to detect network timeout

Recently our BPC nightly job failed intermittently, a few database mirror servers report timeout as well, I need to prove to network team that it's not an application issue, it's a network issue, so I implement the a windows scheduled task to run pathping among those servers every 1 minute. it did prove that network timeout. here is the script and sample of logs.

pingnetwork.bat :
echo %date% %time%
pathping server1
echo %date% %time%
pathping server2
echo %date% %time%
pathping server3
echo %date% %time%
pathping server4

pingnetwork.bat >> e:\dropit\d.txt

the log d.txt looks like this

"

ftp the log file to unix and format it in a readable way.
grep -E "\/ 100" d.txt > d1.txt

the new log d1.txt looks like this:
"

now network is convinced of the network issue and is working on it.
