Thread 'Weird VEEAM Behaviour on Windows VM depending on machine type'

Hi all,

A bit of a weird one here, leaving this here in case anyone finds themselves in the same boat as we did.

Colleague installed a VEEAM backup on a clean installation of Windows Server 2019, wanted to add a Dell DD6400 Data domain as a repository. This was already working on another VEEAM VM in the same cluster, mind you.

No luck, when adding the repository, this error pops up :
