Error de inicio de sesión para el usuario 'sa'

Estoy en el proceso de convertir un antiguo servidor sql (sql 2005) en el trabajo. Necesitamos mantener los datos por más de 7 años por ley. Estoy haciendo esto usando vmware esxi y funcionó perfectamente aparte del espacio limitado en disco (~ 36GB de espacio restante). Sin embargo, el problema es que descubrimos que ya no podemos acceder a las bases de datos desde nuestros accesos directos. Usamos archivos por lotes y los accesos directos están en el escritorio para estos archivos por lotes.

TITLE Checking for Visual 2000 upgrade.  
REM Searches for all the "v2k*.txt" files in the Deploy folder
REM and look if they exist on the local machine. If at least one doesn't,
REM then the deployment is made and files are copied.
REM There should be only one file called "v2k*.txt"
REM Set the folder for the correct deploy folder here:
