I would like to known which DHCP server you are using.  (see below)

Things to next time better:

* Place (big) files on a (web/ftp) server and post the URL of it.
 (realize that you are on a mailinglist )

* say which node is what ( (MAC)addresses of the systemSss in the capture,
 used operating systems, used applications ( name & version of deamons) )

* tell what is going on the network. Example given:
  * Frame   0: server 10.2.2.12 is booted
  * Frame  10: client does first DHCP request and becomes 10.2.2.155
  * Frame  19: TFTP started
  * Frame 305: pxegrub doing DHCP, the point where attention is needed.
