In a new installation of SQL Server 2008R2 Standard in a windows Server2012R2, we have mixed-mode authentication enabled. Using Windows authentication, we are able to authenticate using SQL Management Studio as expected. Using SQL authentication, SQL Management Studio will not let me authenticate. Two strange symptoms:
- Typing in the password field on the SQL Management Studio Connect To Server dialogue has a long lag of about 3 seconds per character typed
- Authentication fails, even though the password is entered correctly
Using SQL Authentication and using another SSMS that is installed in a different server we are able to connect to the instance.
Any Idea in what to do in this cases?
