Hi @DanM ,
The way mentioned by JeffreyWilliams-3310 is the easiest way for SSMS 18.6 to clear items from this list.Just describe in detail:
- Open the Microsoft SQL Server Management Studio (SSMS).
- Open the Connect to Server dialog (File->Connect Object Explorer, Object Explorer-> Connect-> Database Engine, etc).
- Click on the Server Name field drop down list’s down arrow.
- Hover over the items you want to remove.
- Press the delete (DEL) key on your keyboard.
In addition, according to my test, if the windows authentication and SQL Server authentication are both used to log in to the instance, duplicate server names will appear in the server name list in SSMS 18.6 (also 17.9.1), which is a design behavior.
