I thought that it was the work of pxechain (i.e. rewrite the next server in memory to prevent making those kinds of loops).

Hey florent,

That's very surprising as I did exactly the same for installing Windows 
2008 servers and it worked very nice.
Are you sure that pxechain.com is coming from the same version as your 
pxelinux.0 ?
If yes, what release are you using ?

Another question about your DHCP. Does the dhcp server runs on a linux 
host or on the windows one ? If its running under linux, what 
product/release are you using ?
Could you show us its configuration ?

Erwan,
