I've also created a support ticket regarding this issue but just in case it was me missing something obvious, I'd try to reach out in the forum as well.

After upgrading to 9.0 build 9001, I noticed that I no longer had the Windows Domain field. I then tried adding a resource manually - same problem.

I'm pretty sure it's still there on existing resources as my Dynamic Groups based on domain still works (Resource Type = Windows, Windows Domain contains "DomainName").

I also tried adding a resource using Windows resource discovery and that server was also included in the Dynamic Group for that domain so apparently discovery also fills out the Windows Domain.

Anyone experiencing the same or am I missing something?

Best regards

Simon
