Problem with username and password

Hi

I have following problem. I want to test a soap REQUEST. The url is http://192.168.134.250:60022/xxx_TEST/WS/xxxx/Codeunit/Webservicexxx. But I need to provide a username and password (domain/username and password). I have tried everything but I still get 401 Unauthorized.

When I type the url in Internet Explorer, then I get a popup for username and password. If I type the credentials, I see the wsdl file. So that works. But when I want to make a SOAP project in SOAPUI it doesn't work.

Any suggestions?

thx!
