Hello,
I know I can add the following registry key to our existing WDS server (see below) to present an "F11 menu";
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WDSServer\Providers\WDSPXE\Providers\BINLSVC]
"AllowServerSelection"=dword:00000001
...that if pressed, will broadcast for any other WDS servers on the same subnet and present them as menu options to PXE boot from, but what if the other WDS (SCCM DP) is on a different subnet? Our DNS/DHCP infrastructure is not MS, we use Cicso DNS and DHCP and our servers have static IP's (if this matters), we currently use IP helpers to find PXE which we set per location. The goal is to leave our existing WDS infrastructure in-place to serve up our mature Windows 7 image (not created using SCCM or MDT) while still being able to use our SCCM infrastructure for bare metal Windows 10 deployments. I know SCCM can "upgrade" an OS but we're looking at wipe-and-load (party due to McAfee encryption but either way, not upgrading!)...
Thanks for the help,
Jack
