I decided to upgrade to 5.0.2 and PHP is running and the mssql extension is being loaded but it is not able to connect to the SQL server as before. My code hasn't changed and the install seems to be working on other pages. It's only the mssql connect that is bombing. Giving me an "mssql_connect() [function.mssql-connect]: Unable to connect to server:" error. Any Ideas would be greatly appreciated. Thanks
