InfoPath Dev

Hello,
I'm trying to retrieve data from a webservice inside a infopath 2007 formular. If I try to do the operation in preview mode on my XP Client I don't get any errors. If I copy the form to my testserver in order to do the same operation there, I get a error message that says that an error occurd while trying to connect to the webservice. Does anyone has an idea how to solve this problem?
The windows 2003 server is only a member server in the domain. testserver and testclient are both members of the same domain.
Indeed, thanks a lot for your help!

Hello Welcome to the Forums,

In XP client works for preview without any error and it is giving error same steps in other machine means following reasons might be,

          Web service connection might be not available.

          You do not have permission to connect that web service.

Can you try once that web service is opened in Internet Explorer of that machine or not?

Hey Shiva,
interesting - I can open the Webservice in IE on my client machine without problems. On the server machine I have to type in a valid username and passwort first.
Anyway, even on the server machine I am logged in with the same user account that I have used on my client machine.
