Hello!
Problem with the SQL Server installed on a standalone server:
since I needed to create a new Windows login (Windows group login) I first added a a new group in Computer Management (SQLusers, - TestGROUP I added later)...
...and tried to select 1) this group (SQLusers) or 2) another group (TestGROUP ) in SSMS:

- there were no such groups in the Login\Select users or groups window...(but there was a USER account Test I created earlier!). I used to work with domain group logins and never had any issues with adding domain group logins - why this list of available group/user accounts does not include the groups I had created?
There was no problem with creating this login using TSQL:
Q2: The Login\Select users or groups list contains only a subset of all user and group accounts available on the server (you can compare them on the first and second screenshots) - does anybody know based on what SQL is filtering this list?
Thank you in advance,
Michael
