Some Interesting Issues With Solarwind Free TFTP Server

Recently I encountered a IOS upgrade issue. I was trying to upgrade my 3800 Series ISR router. I was using SolarWind Free TFTP Server. But when ever I tried to kicked up the IOS upgradation process I was keep ending up with the error mentioned above.

Everything was fine including L1, L2 and L3 connectivity.

As I was quite sure I was doing it rightly (Actually After couple of months I was performing some IOS upgradation :) ), so I thought to switch over to Cisco's own TFTP server and give it a try....and guys!!!...it worked for me :)

So funny IOS issue indeed.
