you must use the bladelogic provided tftp server. it's available on the EPD site. it's named 'PXE<version>-W<arch>.exe'. you will also need the 'provisioning files'. On the epd site they should show up as:
BMC Bladelogic Provisioning Files 7.6.00 English Microsoft Windows/NT zip 6 MB BMC Bladelogic Provisioning Manager 7.6.00 for Microsoft Windows 2000 / 2003 [x86]
Yeah, BladeLogic it's PXE/TFTP Server. You should set-up proof of concept VPN area to test it that forward the DHCP request to the correct PXE server. Here are the steps to find it at EPD.
On the my entitle products | select BMC BladeLogic Provisioning Module for Servers 7.6.00| Select BMC Bladelogic Provisioning Manager 7.6.00 for Microsoft Windows 2000 / 2003 [x86].
It's kind of hidden. Or logon BMC and click on my hyperlink.
