WDS TFTP loop

[lupowolfi]

Hi,

using the latest version from git (2015.07.07) I encountered an issue while chainloading to our Windows Deployment Server (WDS):
The client gets stuck in a request loop.

Examing the traffic with Wireshark shows the following three actions:

1. TFTP download of wdsnp.com (successful)
2. DHCP request + ack
3. another DHCP request + ack

These three action are repeated infinitely.

Reverting the changes of commit:
edf74df4abf0b9ed92f399272b0491851ba1ffaa [pxe] Always reconstruct packet for PXENV_GET_CACHED_INFO
seems to solve the issue.

Snippet of my script which forwards to WDS server:

Code:

:windows-wds
cpuid --ext 29 && set arch x64 || set arch x86
set netX.dhcp/next-server ${wds-server}
chain tftp://${wds-server}/Boot\\${arch}\\wdsnbp.com
