Well, cannot do. I don't want to add my machine to their domain. I have a domain account. I do not have access to connect via Remote Desktop to SQL Server. I have dbo access to some databases.
All I want to do is to add the SQL Servers to my local SSMS in "Registered servers". But the login window does not allow me to put in another domain account ("se\peterl") when selecting "Windows authentication". I am logged on to my laptop as "laptop\peso".
