TFTP Partial Transfer before failure and then session dying on IOS upgrading

I am attempting to upgrade the IOS on all of my Cisco 3560 switches at remote sites.  I am having issues performing this transfer remotely.  So I am using a management server located at our datacenter as the TFTP source.  I have installed both TFTPD32 and Solarwinds and recieved the same results.  TFTP begins the transfer, gets a significant way through, then pauses and the putty session dies.  The transfer works fine if I have a device on the same subnet of the switch I'm upgrading, but we don't always have that resource available to us and our sites don't have local IT.  I also tried WinSCP but I don't think these switches support SCP (I'm not sure though) I would like to have a consistent and stable method to remotely transfer IOS files to my routers and switches.  Any thoughts?

Why not to try a management

Why not to try a management software- such as a free one from cisco - Cisco Network Assistant, which has a simple drag and drop upgrade feature.
