Hi, This is caused by missing dll's. You need to install the client tools from MSSQL Server on your PHP box. You can also copy ntwdblib.dll from winnt\system32 on the SQL Server to the same directory on the PHP box. If you want to be able to create custome configurations of the client you need to install the tools. - Frank > I got the following error when I tried to connect to MS SQL server: > > Unknown () mssql: unable to initialize module > > Please advise > > > > -- > PHP Database Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
