We are using WDS to rollout desktop images through PXE. We have used this config successfully in the past.
We were required to reconfigure our Cisco switches for a new naming convention. We re-enabled port fast on the switch where the single port that we use for imaging desktops is located.
We have disabled PXE on all onboard NICS, unless imaging the computer, so as not to pollute and consume our DHCP scope with DHCP/BOOTP address assignments.
We PXE-enable the single NIC when imaging, so we know that's the only computer requesting DHCP/BOOTP.
Since reconfiguring the switches, we have been unable to image computers with WDS.
No error message is generated on the client. The client just basically times out, after multiple DHCP requests because of the multiple requests, the scope fills with BOOTP requests and since there are no addresses left in the scope, the client times out (see client screenshot PXE_Boot.jpg).
Running wireshark on the DHCP server and filtering for BOOTP by the client MAC address, you can see only discoveries, no offers or ACKs (see PXE BOOTP Issues.doc).
Can anyone assist?
