Error whith Auth.Authenticate

Hi,

I try to move a working project to Windows 2000 Server

I am using FoxWeb v2.6, FoxPro v6.0 with SP5, MDAC v2.8, php v4.3.8 and IIS6 that come with w2k.

Every thing work fine (active page, forms, navigation etc...)

except when I am trying to Authenticate.

I am getting

---
There was an error during the interpretation of your request.
Error #: 11
Message: Function argument value, type, or count is invalid.
Program: procedure classauth1.passcheck fwauth.fxp
Line #: 365
Line: &SQLStatement
---

I have reduce the code to

---

<html>
<body>
<br> before Authenticate
<%
Auth.AuthTable = 'C:\dataFOX\Users.dbf'
Auth.Authenticate()
%>
<br> after Authenticate
<body>
<html>
---

and I get the same result.

Any help will be appreciate.

Thanks, Francois
