#686 Soap UI : NT authentication keeps popping up

[Aravind]

Hi
I have an issue in accessing a WSDL service using Soap UI. The WSDL is configured with Windows Authentication, and when i try importing the WSDL sevice, it asks for Username and Password. I have provided my Windows credentials and even Service User credentials but the NT authentication windows keeps popping out. If I change the authentication mode to "Annonymous Authentication" followed by "Windows Authentication", the WSDL is getting loaded but then I get "401: Unauthorized" error.
The same WSDL service works if it being called from a Web Application.

Please suggest how to make it work. I have used Soap UI 3.6 and Soap UI 5.0 and in both of them I get "401: Unauthorized" error.

Thanks in advance.

Thanks
