The maximum data that can be transferred in is restricted by the maximum size of the UDP packet which is 65 535 bytes. Some network switches apply ACLs on the UDP fragments as well and might discard UDP fragments if the fragments match their ACL. TFTP in Windows Server 2008 Although the changes mentioned earlier in this sidebar do help to improve the download times it was evident that we needed more for Windows Server 2008. So the WDS team added support for windowing in Windows Server 2008. The idea is that instead of the server sending one data packet and then waiting for acknowledgment from the client the server now has a window of multiple data packets that are sent back-to-back without any acknowledgment from client. The client receives all data packets and then sends an acknowledgment. This mechanism also improves performance in high-latency networks. The number of packets the server should send without acknowledgment is configurable 1. Go to the appropriate architecture directory REMINST Boot architecture . 2. Use the tool to add or edit the window size BcdEdit -store -set 68d9e51c-a129-4ee1-9725-2ab00a957daf ramdisktftpwindowsize window size 3.

If network switches in your environment enforce ACLs set the block size to 1024 bytes and tweak the window size. -Asad Yaqoob Software Design Engineer Windows Deployment Team 430 Introducing Windows Server 2008 EFI x64 Network Boot Support Finally a third enhancement to Windows Deployment Services in Windows Server 2008 is the support for x64 EFI .
