Re: 64 Bit IIS 6 ( 32 Bit mode ) + 32Bit php connect with MS-SQL Server

But having said all of that, the php_mssql.dll uses a very old library which may give you issues. For the time being, using ODBC (php_odbc is built in for PHP on Windows) is a much safer solution. You can also use the latest SQL Native Client driver so you can talk to SQL7, 2000, 2005, 2008. If you are used to using a DNS-less connection, then ... $Conn = odbc_pconnect("Driver={SQL Server Native Client 10.0};Server={$Server};Database={$Database};MARS_Connection=Yes;", $User, $Password, SQL_CUR_USE_DRIVER); will give you the connection without the need to have a DNS entry. -- ----- Richard Quadling "Standing on the shoulders of some very clever giants!"
