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?

I would use SCP. We have the same problem on occasion.
Something like this command wise -
copy scp://username:password@192.168.1.250/filename flash:filename
Solarwinds SFTP/SCP server http://www.solarwinds.com/products/freetools/free_tftp_server.aspx

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.
