Problem is that support seems to be a bunch of Proseries customers that are doing support for a discount on Proseries. 

We deployed a 2019 server standard for file server , on a Windows Active Directory Domain, PIV Card Cert Authentication, Server had 4x SSD in raid 10. Worked awesome this year. We had around 6-8 preparers, i'm sure it could handle a ton more. No more Windows 10 pro connection limits.
