Hi, One problem could be name resolution. The mssql server uses a default protocol to connect to the server. If you just install the client libraries (or just copied ntwdblib.dll) the default protocol would be netbeui (named pipes) and that might not be routed/enabled on your network. To make sure your client can connect to the server you should configure the client network utility (a program installed with MS SQL Client tools). You can use this application to set the default protocol, and you can create aliases that combines a name to a server through a specific protocol. Another problem could be the configuration of the SQL Server. Does it allow SQL user names or does it require a trusted connection. Use mssql.secure_connection = 0 or 1 in php.ini to alter this. - Frank > Hello. > I have a sql server named CLUSTER01, i try to connect to it : > $db_conn = mssql_connect("CLUSTER01", $db_usuario, $db_password); > > and it gives me this message: > Warning: 0 is not a MS SQL link index in x > > The user name and password are correctly created in the logins of the sql > server. > What else could be? > > Thank you for your help. > > -- > PHP Windows Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
