'[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user' error

Question

I am trying to connect to a local network SQL server via excel VBA but I get this run-time error:

[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'myUID'

When I use this connection string

ConnectionString ="Driver={SQL Server};Server=myLocalServer; Database=myDb;trusted_connection=yes;UID=myUID;PW=myPWD;"

I have Windows Authentication as the Authentication Method for the SQL server.

Do I need SQL and Windows Authentication? Is there something wrong with my connection string?

Solution

If you set a UID and PW, then it's more than likely a SQL account. Does that account exist in SQL? When you remove UID AND PW, and replace with a trusted connection, it's then using windows authentication. If you do this, make sure your windows account has permissions in SQL.
