Connection Error

Dear Guys

I had installed MiniSAP 4.6D in my system and visual studuio 2003. I am trying to connect an ASP Login Page with MiniSap. I developed this page using C#. SAP.NET Connector is also installed in my system.

But when ever I tries to connect the ASP.NET page with SAP I am getting error

<b>You are not authorized to logon to the target system (error code 1).</b>

User ID , Pasword , Host System and System Numbers parameters are also correct.

Kindly help where the actually problem is. Is there something which I am missing. Any link to step by step guide. Please note that I have read the .Net Connector documentation already and its not helpful i my case.

Waiiting for our reply. Thnx
