Problems With DHCP Option 43

Be aware that DHCP option 43 breaks a lot of stuff. In the past, I noted that using APCs necessary binary value in DHCP option 43 will break DHCP configuration on HP JetDirect boxes. Now, I have also found that it breaks PXE boot on HP DL360 G3 and G4 servers. With the option enabled on scopes serving machines that need to boot PXE to talk to an HP SIM (Systems Insight Manager) or RDP (Altiris Remote Deployment Pack for SIM), the PXE boot fails and displays a PXE boot menu error and automatically reboots. This option is normally deployed globally on the DHCP server. I suggest removing it and only adding it back at the scope level in situations when you must have it. Then remove it when you are done with it.
