The IP helpers? Definitely need them. The DHCP options? No, no, no!
In fact, setting DHCP options can interfere with successful PXE booting when IP helpers are in place. I highly recommend that DHCP options not be utilized.

Also, options 66/67 may need to be set on your DHCP scopes to point to the boot server and boot file.

It's been a few years since we attempted this but I think there was also a DHCP or DNS setting that needed to be changed/added. It's not just SCCM setting unfortunately.

We are migrating our imaging process from MDT over to SCCM. The server we were using for MDT is Server 2008 standard and has been added as a distribution point in SCCM it previously had the WDS role installed on it to distribute the MDT boot images over PXE. I put together an SCCM boot disc using the instruction posted by Johan here: http://www.deployvista.com/Default.aspx?tabid=70 <http://www.deployvista.com/Default.aspx?tabid=70&EntryID=54> &EntryID=54 I'm trying to enable multicast and PXE using SCCM so I removed the WDS role from the server, waited a few minutes, then went to the DP properties in the SCCM console and checked the box to enable PXE and Multicast. I enabled the OS images, boot discs, and task sequences to be transported via PXE/Multicast. I can see that SCCM reinstalled the WDS role on the DP (I don't see any other configuration when looking at WDS for boot images, figure it's all handled within SCCM) but when I try and PXE boot a client machine on the same subnet it is unsuccessful. The SMSPXE.log entries from the DP are below. It basically gets a DHCP address and then says that no boot filename is received. Not sure if I missed a step, or if there are problems because of previously having WDS installed on the box, or if I've got something completely wrong some where else. For what it's worth, if I boot from the disc I created using the Johan instructions over PXE it works fine and I am able to complete task sequences. Also of note, these logs are from brand new computers that haven't touched our domain yet and are not in SCCM. I have task sequences deployed to unknown computers and enabled unknown computer support on the PXE boot options of the DP.
