[Wlug] odbc help

Has anyone ever gotten a linux box to speak to a MS SQL server? I am only assuming i need to configure an odbc DSN from linux to MSSQL, but am not successful yet. The end goal is to get phpBB2 to talk to my existing MSSQL database. In order for that to happen, apache has to use php and php has to use an odbc connection to MS SQL. Well, php in apache is working now, and php is set to use MS SQL. isql -s SERVER NAME PWD connects me to my MS SQL database just fine, but iodbctest is failing. I don't know enough to know what is wrong. Any help would be greatly apreciated! mike
