I have a identical system as virtual machine (vmware) and a physical server with windows 2008 and sharepoint 2010.
I am using the WebClient to download an image (c#). that work absolutely fine in virtual machine but in physical server the image size independent from original size are all about 12 kb or 13kb !!!

I tried also from physical server to download file using same code from internet (random free picture) and from my virtual machine. that work fine doesn't matter which file size.
but in opposite way from virtual machine using the code to download from physical server again give me 12kb!

i think it could be a configuration issue on physical server...

I would appreciate any help
Thanks
