We also have the Dell Latitude E7450 model, in the clean boot.wim you have many drivers but of course not drivers that were created after the WinPE version. If you add the Windows 8.1 drivers of the NIC and the storage controller (you find them on dell.com) it will work.
Yeah I went and downloaded the drivers from their website, injected the 4 .infs for 8.1 x86 and that part works now!
Now I'm getting to the template but it's failing at deploying image due to a credential issue I think? Where does the template get those credentials from? I changed some stuff around recently but I thought it was working before...
edit: Ok my IMAGES share had completely disappeared somehow... hope it works now!
Credentials are acquired from the Preferred Server config.
OK yeah I changed all those creds back to my domain admin account and it's still giving the same error. It was definitely working before on other computers so I'm totally lost.
The error log shows
Mapping to \\bhfs\LANDESK\images\win7office365-2.tbi
Drive letter = e
Mode - attempt preferred server
Could not get credentials for preferred server
End of map drive. path used: - \\bhfs\LANDESK\images\win7office365-2.tbi
drive letter = e
could not map or unmap drive. error code: 2250
end of unmap drive
I've done this like 10 times on another computer and it always worked completely fine. Then I try this computer and I have to remake my boot.wim, inject new drivers, and now whatever this is... I better try another computer just to see if I'm crazy
Are you sure that E: is available on that machine? when the template errors out open a command window and try to manually map E:. I would suspect that it might be already occupied.
Yes there are no other maps. I can manually map it fine with net use. The issue has to be with the preferred server. I added in a template action to manually map the drive with my same credentials and it works fine. But if I do that, then maptopreferredhandler.exe tries to map again to F: and it fails. Is there a way I can skip maptopreferredhandler.exe and just deploy the image from my manual drive map?
I believe there was an issue with the drive mapping in 9.6 but I thought that it was supposed to be fixed in SP2.
Like I said it was working last week and the only thing I remember changing was the credentials to service accounts instead of my admin account. But I changed those back and it's still not working. It's like it can't find the preferred server at all or something. I put in a ticket to support as this is really urgent so hopefully I can get a work around....
I found a work around that at least has gotten the computer to start imaging, I added a manual Map Drive action and changed the Deploy Image action to 'Other' and linked x:\ldprovision\imagew.exe and used the same default parameters we had before.
I'll see how the rest of this goes to see whether I need to keep working on it or if this will do as a permanent solution...
I was going to say that the work around before was to just add a map drive. It is odd that there is not the same issue with other model machines.
I just wanted to share a link:
With this, you don't have to get every driver individually. Also, you could use imagex to manually add multiple drivers at once.
