I wanted to upgrade to XAMPP 1.7.3 from 1.6.8 but cannot get the MSSQL connection to work, I always get "Unable to connect to server".
The exact same php code works with the exact same MSSQL server on 1.6.8 but not on 1.7.3, so I can rule out password and MSSQL configuration issues.
I am using extension=php_mssql.dll and extension=php_pdo_mssql.dll.
I tried replacing the ntwdblib.dll 8.00.194 that comes with 1.7.3 with the one that came with 1.6.8.
Does anyone have any ideas?
