ODBC error

hi everybody, when i call to my file (my_file.php), the next error occurs: [the scenario] Winnt 4.0 SP6 IIS 4 php 4.0.5 [my_file.php] <?php $con = odbc_connect('the_dsn', '', ''); odbc_close($con); ?> [the error: i translated it from the spanish (or at least i tried to...)] Warning: SQL error. [Microsoft] [Microsoft Access ODBC Driver] The Microsoft Jet data base engine can't open the file '(unknown)'. It's opened in exclusive mode for other user or you need privileges to read it., SQL state $1000 in SQLConnect in C:\the_path\my_file.php on line 5. however, nobody has opened the data base and i actually have all the privileges too. I've put the file and the data base into another different computer (with the same operative system and configuration) and everything works perfectly. Tip: With a similar asp file i have no problem: [my_file.asp] <% set con=server.createobject("ADODB.Connection") con.open "dsn=the_dsn" con.close %> any advise? thanks in advance, galfano carboni.
