Testing WCF Service with SOAP UI 4.5.1 Error 401

Hello All,

I have deployed web services on the server.

1. I get the error as "401-Unauthorized: Access is denied due to invalid credentials". When I submit the credentials it just shows the processing bar and nothing happens.

2. In addition to this (to test if I am going wrong anywhere) Can someone please tell me the steps to configure SOAP UI to test the same?

Please help me.... Thanks,
Amit
