Hi Guys,
I wanted to give you a heads up.
We have had a huge PITA to get our E5500 laptops networkcards working in WinPE for MDT deployment.
Especially with these WinPE cab's.

This is due to the fact that the correct revised drivers are not anymore in the WinPE 3.0 package and WinPE 4.0 most certainly does not contain them.
I had the luck of having another customer that I set up this system for a couple years ago who still had their old WinPE 3.0 package in place.
Their package was version A07 (very handy that you can get the old versions on the website, not...)
And the current version is A12, our models instantly worked with A07 and did absolutely nothing with A12 (i.e. error about not being able to contact the deploymentshare due to the lack of connectivity)
Just wanted to let you and the internet know, I don't know the appropriate channels to get the right driver back into the WinPE 3.0 cab again.
But maybe, when you are reading this, you do. Please be my guest because it saves everyone a world of trouble.
