I am rolling out Windows 7 Pro to 200 users.
I had a test lab of our new Dell 780 PC's and everything was fine i.e the machines would boot via PXE to WDS (without DHCP scope options) and then get a custom unattended image installed....great
We have about 50 older Dell OptiPlex 755 and 745 PC's - These boot and come up with various PXE errors e.g PXE 51, PXE 55, No dhcp response on proxy DHCP port 4011 (can't remember exact message).
As we had DHCP on a different server to WDS I then configured the options 66 and 67.
Now these PXE errors go away but PXE now gets stuck on MTFTP
Q. Why teh difference - I must be honest I didn't forsee such and issue as the 780's have allways worked fine from Day 1!
Only difference I can see is the Intel Bootmanager/Bios version:
780's have 1.3.52.
755'2 have 1.2.50
Anyone have any ideas on what to do?
