OUR PRECONDITIONS

  • The old network infrastructure, referred to as OldNet:
    Doesn’t support 802.1x.
    Two domains on different VLAN’s with a one way trust, referred to as Enterprise and Educational.
    The two domains have their own network infrastructure, different IP Helpers, DNS, DHCP and so on.

  • The new infrastructure, referred to as NewNet:
    802.1x is required using CISCO ISE and Layer 3 switches.
    Only one fallback net with its own IP range, common for both domains, which also supports WebAuth guest access.
    The two domains still have their own IP range, DHCP, DNS etc. but will use the same PXE-server since PXE boot is taking place on the fallback network.

  • Both the old and the new network infrastructure will be used to deploy Windows 10 x64 and Windows 7 x86.

  • MAB will not be used during OSD, the network team don’t want to spread a special OSD VLAN so clients will get an IP address according to its current location and only certificate-based authentication is allowed.

  • The task sequence needs to support both the new computer and refresh scenario as well as BIOS to UEFI conversion regardless of the currently installed operating system.
    The scripts used for managing 802.1x needs to support Windows 7 and its PowerShell version.

Early TSEnv-persistence

To do something manually and then try automate it is for sure two different kind of things.

I could have just written about how to set a TSEnv-variable that’s persistent after an “old version media”-reboot but that’s just not me. When I post something I want to include a practical example and experienced some of the issues that might occur.

And there’s where the troubles began. :P

As I’ve said, to set a TSEnv-variable early and make it persistent isn’t a problem at all. But to make use of it, not too early nor not too late, is.

Too late and the TS has already begun and too early you can’t cheat the environment. Working on it and I have no doubt that I will be able to present something that works in most, if not all, kind of scenarios. Got a family to take care of foremost and I’m doing most of these things on my spare time, since I'm having other directions at work, so might take a week or so before I got something that’s worth presenting.
