Getting the error above on a Windows 2012r2 VM, that previously ran 10.3.1 with no issues. VM is for development, not on a domain. However I also have two VMs in production that when testing 10.6.1 have the same issue.
I have double checked permissions on all folders, opened up ports and gave the exe's permission through the firewall.
