ISSUE RESOLVED.
We have 2 identical machines running Windows Embedded Standard. We installed 1 last week, got it connected to the domain, but we cannot map any network drives or even directly navigate to them. We can ping our DC and remote desktop to them. We installed the second yesterday and had no issues whatsoever. We verified all the settings between them, swapped their switch ports, etc to try and troubleshoot this issue, and assigned static IPs, but have had no success.
Any advice or tips/tricks? My google-fu has been unsuccessful.
(I'm just a desktop support tech, so some of what we have done is above my paygrade, but if you ask, I can ask my boss.)
