I am using Windows 7 RTM, and things are running smoothly for the most part. My Windows 7 installation is the default, out of the box configuration.
I am using the standard TFTP utility available with Windows 7. When I attempt to upload a 3 kb text file to our internal TFTP server, it always time's out. However, TFTP'ing the same file, on XP (from the same network port — different laptop, but same model) it works perfectly.
Is anyone aware of any default configuration on Windows 7 (or even) Vista that could cause this?
