What's so great about the MDT / SCCM integration, specifically about task sequences and OS deployment?
I understand that using MDT to build an image is preferable for a lot of reasons, and I'm okay with that part. It's the MDT-enabled task sequences that are bothering me. It seems like whenever I need to create an MDT task sequence, I have to bend over backwards, analyze everything in the task sequence created, tweak the defaults, pat my head, and rub my tummy before it will (somewhat) work correctly.
Here's my latest example: I needed a fairly simple refresh task sequence to be run on about fifteen computers of a single hardware model. I'm not concerned with preserving any data on them; I just need to format and install Windows, along with a set list of applications. I'd like to use copyprofile as well, so I turned to MDT instead of building my own unattend.xml from scratch. My MDT task sequence is now three times as long as my original "vanilla" task sequence was, contains unneeded variables for BitLocker, UEFI, and the UDI wizard, and it still fails! I get seemingly random 80040005 errors throughout the task sequence with no apparent rhyme or reason (they actually happen in different places in the same task sequence on the same machine) with no output in smsts.log. The SMSTS.log files are now stored in about four different places. In fact, when I create a new MDT task sequence without selecting the UDI wizard and try to run it from within Windows (using the Software Center), it doesn't even restart into Windows PE - I get an error when it tries to partition Windows from within Windows.
I'm fairly new to MDT, so it's very possible I'm doing this wrong...but from my perspective, integrating MDT with SCCM has been nothing but a headache. Could anyone explain some of the advantages of using these enhanced task sequences?
