What version of the php_mssql.dll are you using ? 
We had an error a while back where mssql_query returned a wrong value (true instead of 
a ressource).

You could also add an extra parameter to the query function

$answer = mssql_query("SELECT * FROM table", $connection);

P.S. If you are using an old version you should be able to download a new from 
www.php4win.de.
