I’m a new bee in this kind of setup, I’m using Windows 2003 SP2 with WDS configured, and I’m facing the same extremely slow connection on the client box. I need detail step by step instruction to increase the TFTP block size to speed up this process. Any help will be highly appreciated.

Thanks for the reply. After reading info from the link you pointed out, I installed Windows 2008 and configured the box as DC, DHCP and WDS and it worked just fine. Thank you so much for all your help.
